The Construction Historian took a wee trip to Trimontium this week and really loved the signage up on Eildon North (1 of the 3 hills from which Trimontium takes its name). Beautifully carved in a Roman style to point you to the correct paths up the hill.
Please use main path  carved into three stones.

For the Safety of All: Scotland's Lighthouses
3 August – 25 September 2026, Monday-Friday, 09:00-16:00

The stunning coastline of Scotland and its islands have provided a livelihood for its population for centuries. While beautiful, it is one of the most treacherous coastal waters in the world.

Our fascinating archival exhibition celebrates the history of Scottish lighthouses, the establishment and role of the Northern Lighthouse Board (NLB), and the unique occupation of the lighthouse keeper. This exhibition examines the construction of the world’s oldest off-shore lighthouse, the Bell Rock, and displays original records documenting the disappearance of the three lightkeepers of the Flannan Isle Lighthouse in 1900.

The Construction Historian enjoyed a fun day out in Aberdeen. This very mixed-media wall is at the site of the former Aedie's House (details in ALT) and goes to show that Aberdeen isnt/wasnt all granite. The other mixed-media image was lunch.
Wall of granite rubble and brick with various left-behind scars of chimneys etc. ANDREW AEDIE'S LODGING, THE GREEN, ABERDEEN
https://her.aberdeenshire.gov.uk/Monument/MAB57082/
Site of a town house which was demolished in 1914. The Aedie family house stood on the north side of the Green at the corner of Aedie's Wynd, now known as Back Wynd. The house had possibly been built by the master-mason, Andrew Jamesone (father of George Jameson), for Andrew Aedie, maltman, who died in 1604. His initials along with those of his wife, Christina Guthrie, were on one of the skewputts. The building was of three storeys made of harled stone walls and had a steep pitched slated roof. It had an unusual feature of a wide chamfer at the south-west corner between the first floor and the eaves, where the skewputt was carried on three rounded corbel courses. There were latterly shops at the pavement level and at the second floor there were three fine dormer windows, added by David Aedie in 1633, whilst the west dormer tympanum has his monogram/initials and coat of arms. In the middle there was a complex monogram of the initials DAE and KB for his wife, Katherine Burnett bearing the date 1633 and a shield carrying the combined heraldic arms of Aedie and Burnett. Davie Aedie was one of the many townsmen killed by Montrose's troops at the Battle of Aberdeen near Justice Mills in 1644. Mary Jamesone, daughter of George Jamesone, married George Aedie in 1677 and may have lived in the house until her death in 1684. She is most widely known for her embroidered religious panels that hang in the West Kirk of St. Nicholas. The house was demolished in 1914 during refurbishment of the Green and expansion of Union Street. The outline of the roof and some of the sandstone still can be seen on the adjacent property on the Green.

It might have been mentioned before, but the Construction Historian cannot resist picking up a brick.... Whilst on a day out with the Panel on Historic Engineering Works, in Ayrshire, we passed this derelict mill at Laigh Milton near Kilmarnock. This brick was rescued from there. More info in ALT
Milton Mill. It was at various times a lint mill, seed-cleaning mill and a hone mill (making sharpening or honing stones). In more recent times it was a hotel and restaurant for decades but has been derelict for over 10yrs now.
More here: https://www.ayrshirehistory.com/ref_mills_of_the_river_ayr_hume.html Brick from Tho King & Co, of Bellside, Lanarkshire.
The use of reversed lettering was commonplace at one time: each worker had a unique mould pattern so that all the bricks seemed to say the same thing but each was slightly different, eg by reversing one or more letters. This was so that the worker could be paid for the number of bricks they made.

The Construction Historian has had a wee holiday in the south of England and seen some nice castles. Bodiam has some classic examples of what happens to sandstone when you use portland cement mortar plus how much better a bit looks that has had proper #lime mortaring. @limefinishes.bsky.social
That dark grey covering just above the water is old concrete probably applied in 19thC when Joseph Cubitt owned the castle. It is not helping so it will be removed at some point in the next few years.Sandstone in the main entranceway suffering badly from 19thC concrete mortar.

CHS has had this query. If you can help, please DM us and you will be put in contact with the enquirer. Can members of the CHS suggest where the enquirer might find historical/biographical information about J. Henry Dyke and , if possible, a photograph of him ?
An appeal for help from The Netherlands about a British construction company. 
Mr Jacques Lemmink is researching post-War Reconstruction (1945-1965) of Bergen op Zoom in the Netherlands, with a view to publication in late 2028: 

"During my investigation, I was struck by references to an English construction engineer named J. Henry Dyke. My drive is to give this person more ‘body’ in my publication and thus also in Dutch historiography. Why?

The Simplified Brickwork house, also known as the Davis house, is a unique building type that emerged in the UK between 1934 and the 1950s. Designed by J. Henry Dyke and manufactured by Simplified Brick Construction Ltd, (patent GB402426) 11 Old Jewry, London EC2 these homes were part of a broader movement to provide affordable and durable housing during a period of significant social and economic change. Approximately 700 of these houses   were built in England during the pre- and postwar period, primarily as bungalows and two-storey semi-detached houses. They are characterized by their steep pitch gable roofs covered with concrete tiles and external walls made of brick or rendered throughout. In Dutch historiography Dyke is often mentioned as inventor of the ‘Simplified Brick Construction’ (SBC), an assembly line production of wall elements.  He has almost the status of a ‘godfather’, but no serious building historian gives any biographical information about him.

In the Netherlands between 1950 and 1980 c. 450,000 prefab houses (systeemwoningen) were built, often using a British system, e.g. Airey, Orlit etc , approximately 15 % of the total production of new dwellings. Approx. 30,000 of the SBC 'system built' houses were built , more than in the British Isles.

In my view it is strange that we know in the Netherlands so little about the man who stood in 1934 at the cradle of SBC-building system.

An appeal for help from one of our CHS members. If you know where to get this paper, please let me know so I can put you in touch with the enquirer.
"I am a fellow researcher at the University of Granada. I am conducting research into historic bridges in Andalusia and would be very interested in consulting the second part of an article, the first part of which was published in *History of Technology* in 1986. The article is: 

J. G. James (1987)
“The origins and worldwide spread of Warren-truss bridges in the mid-nineteenth century. Part 2: Overseas development and diffusion”

Unlike the first part, this second part was not published as a standard article and, as far as I understand, is circulating as an academic offprint or copy in university libraries.
I thought that perhaps you or a member of the CHS might know where this work can be found. If you could help me track it down, I would be very grateful."

The Construction Historian loves nail history but also the story of how the Norwegian Stave churches were built with hand-cleaved planks. Norwegian government funded major research into how to split a tree into 8 planks. One of the most fascinating papers I have heard at any CHS conference.

The CHS 2026 Conference Cambridge, 25-27 Sept 2026 will have 1 of 2 days on Building Practice: regulation, corruption, & adaptation. This fascinating talk is about how water systems were built for London & , towards the end, some very definite corruption & bad practice. youtu.be/hfOJpQmPIc8?...
The Mercenary River’ by Nick Higham

Today we take water for granted. Turn a tap and the stuff gushes out. But for centuries London struggled to supply its citizens with reliable, clean drinking water.

Nick Higham tells the story of London’s water from the Tudor era to the 20th century. It’s a tale of remarkable technological, scientific and organisational breakthroughs, but also one of greed and complacency, high finance and low politics. London’s 19th century water companies operated a cartel which worked in their interests, not their customers’. The water they supplied was overpriced, deficient in quantity and frequently filthy – described by one scientist as “diluted sewage”. It took the best part of a century of campaigning to bring the water companies to heel.

#WHM Nailmaking was frequently 'women's work' perhaps because it was working with minimal equipment, small pieces of metal, could be done in the home, & above all was badly-paid. A girl would be expected to produce 250 nails an hour.
Girl nailmaker: pointing spike nails 1889.Extract from Women Nailmakers in 19th Century Scotland, by Dr Nina Baker, TATHS newsletter #93, Summer 2006.

Christina Mason was the widow of John
Provan, a manufacturer in Glasgow, who
died in 1858. For nearly twenty years,
from1860-1879 Mrs. Provan is recorded
as a nailmaker at 145 Garscube rd,
Glasgow; nailmaker, rivet maker and
chaplet maker, at Cedar Road, off
Garscube Rd; at 127 or 129 Garscube
Rd, Glasgow; at 311 Garscube Rd; and
finally at 12 or 22 Palm St, Glasgow.
She is not recorded in the directories
after 1880. Her home was at 128½
Garscube Rd. In 1869 a David Provan
(whom I presume to be either her son or
a relative of her dead husband’s) was
apparently involved at the same address,
but in 1871, 72, Mrs. Provan is listed,
again working on her own. Wills are
available for John and David, but not for
Christina. Garscube Road is nowadays a
bit ‘rundown’, but it continues to have
various light industrial workshops along
its length.

#Construction #History #WW2 History hivemind - has anyone got any ideas to answer these queries on FB? www.facebook.com/groups/homef...
My visit to the air raid shelter on Diglis Island yesterday threw up some extra questions. 
1. Is the build style of precast concrete sections bolted together the usual construction ?
2. It's 15 sections each side which I assume is space for up to 30 people. Is that correct ?
3. Most of the sections have similar "Graffiti".on them. Is this period or later ?
4. While talking with my escort, I suggested that the skylight visible in the last photo was a modern thing. Yes ?

Loyal followers may recall that the Construction Historian loves old bricks. #TIL from @mininglandscapes.bsky.social that these are part of the "heavy ceramics" category: www.mining-landscapes.org/blog
Collecting Scottish Heavy Ceramics
Tue Jan 13 2026

Ian Suddaby

To be honest, the term ‘Heavy Ceramics’ is not one I’ve ever used so it seemed like a good idea to consult Google at an early stage.  Apparently, bricks and tiles are included in this category, alongside heavier items like industrial pipes, troughs and decorative pieces for home and garden. For the purposes of this summary, I’m going to exclude ‘light’ items like standard sized bricks and tiles although some of those can weigh over 6kg.  Included will be larger refractory special shapes and the above range of products. Most are made from fireclay, with some being salt glazed. A few are made from surface clay deposits.

Construction History Origins and Consolidation of a Discipline International Symposium a tribute to professor Santiago Huerta Main Hall of the School of Architecture (ETSAM), Madrid (Spain) November 13 and 14, 2025 blogs.upm.es/homenajesant...
Presentation

Santiago Huerta retired this year as a professor at the Madrid School of Architecture after more than thirty-five years dedicated to teaching and research. His thesis, presented in 1990, focused on one aspect of the History of Construction: traditional masonry construction, and this has been his main field of research ever since.

But he did more than just research. Since joining the school as a professor, he has not limited himself to teaching the required subjects but has also launched a new course on the History of Construction. He was also involved in the management and promotion of the Programa de Doctorado en Estructuras de la Edificación, which remains active after its accreditation was renewed, and participated in the creation of the Máster Universitario en Estructuras de Edificación, which is now in its eighteenth year and has enrolled more than five hundred students.

The whole article is fascinating in that it begins with the case of a female bricklayer who had been living & working as a man for many years. Came to light due to a marital court case. Widely covered in the press.
 Morning Chronicle - Friday 13 April 1838 
A FEMALE HUSBAND IN MANCHESTER. In The Manchester Times of Saturday last a paragraph to the following effect:- " UNFOUNDED REPORT.-A silly report has been indus- triously propagated this week, to the effect that a respectable female in this town has been married for about 17 years to a person who, within the last few days is discovered to be a woman. As it was not impossible for such a circumstance to have occurred, although very improbable, we had curiosity enough to make Juql tries onl the subject, and Ibund that the alleged ' remarkable discovery' was a gross fabrication." We, too, have had curiosity enough to make inquiries on the subject, and find that the " unfoanded report" of the " re- markable discovery," which, though " not impossible," is " very improbable," is true. All the circumstances commu- nicated to us relative to this singular case we do not feel justified in publishing; but we way mention a few of the principal facts connected with what is here known of the history of this Chevalier ?? in humble life, of course suppressing the names ef the parties. A few days ago a respectable ibmale waited upon an attorney in this town, and asked his advice in a case of a very peculiar nature. It seems that ber husband a master bricklayer, who had been in the habit of trusting her implicitly in his business, even leaving to her management the bookkeeping requisite in his trade, had of late, tbr souse cause or other, refused to allow her the weekly usual sum for holeekeeping. Having also, in other re- spects, treated her as she considered in an unkind manner, sile came to take advice as to how she should proeeed, under the circuimstances, against her husband, whom, to the no small astouisliment of the professional gentleman she was then consulting, she declared to be, not a man, but a woman. The attorney thought it his duty, under such singular circumstances, to bring the matter under the notice of Mr. Foster, the magist… Several articles clalinea DE 1nte wvae been sent to the police-office by the husband, who, so far as we have heard, has not offered any reparation to the wife for the cruel and painful position in which she is now placed. One thing is tolerably certain, that after the exposure which hass tken place, and the affdir was currently talked of as early as Thursday and Friday last, the woman who has ven- tured to assume the charatter of a loan will no longer be able to continue to carry on business in this town, and that she must either lay aside her disguise and resume the ap- pcarance whieh most befits her sex, or, if she will retain her unfeminine appearance and character, she must Peek to hide her imposture in some place where she is not known, and wvere shg may hope for a while to escape detection. We believe that many persons who have employed her join in declaring that they had not the slightest suspicion that she was other than what she seemed. It is somewhat reinarkable that this is not the first case of this nature which has been brought under the notice of Mr. Thomas. In January. 18219, a labourer in the service of Mr. Crisp, shipbuilder, at Duckhead, London, while assist- ig in sawing a log of fir, was struck by the severed part of the llg with such force on the head as to die of the injury while being conveyed to St. Thowas's Hospital. OR strip- ping the body to prepare it for interment, it was discovered that the deceased, who was about Jil years of age, was a woman. She had been known fur about 22 years to have filled various situations, as groom, 8hiipwrihgit'e la- bourer, and other subordinate ocupa tlon in oocK-yrarrs, vitriol-works, &c.. and had been twenty-one years married, and his wife declared in the most soleinn manner, on the inquest, and beibre tie police magistrates at Bow-street, that daring the wlhole of that period she had been in utterig- n tranca of the real sex of her supposed ?? ter Guardian

CONSTRUCTION HISTORY & FILM INTERNATIONAL SYMPOSIUM 19 - 20 february 2026 CALL FOR ABSTRACTS 6 November 2025: spehc.pt/CHFilmabstra... More at : www.spehc.pt/noticias.html
The symposium marks the first step towards creating an academic forum dedicated to exploring film images as a valuable source for the study of Construction History. By bringing together scholars from diverse fields, we aim to foster discussion, share recent research findings, and open new perspectives in this emerging area of study.

Since the late nineteenth century, moving images have captured every aspect of daily life in communities around the world. As with earlier artistic media, motion pictures revealed the everyday realities of new construction in urban, rural or natural landscapes as well as restoration and maintenance of existing structures. Newsreels and documentaries are among the main categories of historical sources providing valuable insights into building practices since the invention of cinema. These films document the extraction, transportation, and use of materials, machines, and building techniques, the activities of architects, engineers, master builders, and work crews on construction sites, as well as in their leisure time. They also document a wide range of events, including foundation-stone ceremonies, inaugurations and trade union demonstrations, among many others.

🧵This weekend the Construction Historian and the CH's son and pals have been doing back-to-basics forestry. Using a 2-person crosscut saw and wedges to cut up and cleave a cherry tree that came down in Storm Eowyn. We now have some partly cleaved lengths that may (MAY) 1 day be usable timber. 1/3
The cherry tree and the saw.
It took a very long time to cut the trunk from the rootball and then to cut the nearer length to separate it from the  bigger bit beyond the huge knot where the trunk divided.
We love our saw, from Flinns.Marking the cleaving line with a sooted string. 
Luckily we had plenty of charcoal for sooting the string, from a BBQ the night before.Starting the split with wedgesAxe and wedges creating the cleaving line.

Chester is a former Roman fortress town located on the River Dee. Its proximity to the Welsh border made it a
key defensive site for the English monarchs, especially in the thirteenth and fourteenth centuries. Many of the
city’s buildings were constructed using a distinctive red sandstone which can be found throughout the region,
including the walls, castle and cathedral.
Chester Cathedral has a rich and complex history. Its origins may date as far back as the late Roman period,
but the earliest phase of the present building dates to 1093, when Hugh Lupus, Earl of Chester, established a
Benedictine abbey on this site. The building is nevertheless best known for its impressive Perpendicular
architecture and innovative vaulting structures, which are the product of a long phase of rebuilding starting in
the thirteenth century.
The earliest of these new Gothic structures are to the east of the cloister and include the rectangular Chapter
House with its lancet windows and early tierceron vaults. These were followed by a more ambitious project to
build a complete replacement for the abbey church’s east end, starting with the new Lady Chapel. The
rebuilding of the choir was a prolonged and disrupted process and continued well into the fourteenth century.
The final stages of premodern rebuilding, which include the west front, the roof of the north transept and a
revaulted cloister, date from the fifteenth and early sixteenth centuries. Chester thus preserves architectural
styles from across the Gothic period and is an especially rich repository of complex vaulting structures.
Today, Chester Cathedral is a vibrant community of worship, an archaeological treasure, a cultural hub, a
centre of musical excellence and a unique blend of medieval and modern history.While at Chester, study day attendees will be among the first to see the results of ‘Centring the Past: The
People and Skills in Making Medieval English Vaults’ (University of Liverpool, AHRC IAA), a cross-sector
project that bridges the divide between the abstract knowledge of historical craft and its practical application
in Britain’s premodern builders. The morning’s workshops will demonstrate how textual evidence, digital
analysis and lived experience have been used to investigate the lost carpentry involved in raising medieval
vaults.
Following this, the group have an opportunity to explore material relating to the cathedral’s building fabric
and vaults in-situ and in the library. Discussion will focus on how interdisciplinary approaches can inform the
understanding, conservation, and the care of built heritage, and what role experimental archaeology can play
in our research. Throughout the day, there will also be opportunities to engage directly with full-sized and
scale reconstructions of thirteenth-century vaults and timber formwork as well as talk with the craftspeople
involved with the projecProgramme:
10:00 Delegates arrive in Abbey Square, Chester Cathedral, before moving into
nearby 30 Werburgh Street for tea and coffee.

Cahilly-Bretzin (University of Liverpool).
A discussion on the intersections between academic research, digitisation,
practical knowledge and experimental projects.
12:00-13:00 Session 2: Cultures of Care at Chester Cathedral: A roundtable with
Chester Cathedral Clerk of Works, Collections Manager, and others.
13:00-14:00 Lunch break.

Cathedral collections, led by Emily Lanigan-Palotai (Collections Manager,
Chester Cathedral).
16:00-16:30 Concluding remarks
The study day will conclude at 16:30, but delegates are invited to stay for Evensong at 17:30.Applications
The cost of the day will be £25 for BAA members. The event is free for students, for whom travel grants (to a

CAHS Easter Term 2025 - Studying water and architecture - does infrastructure belong in architectural history? Lecture 12 May, by Professor James Campbell. Link to register in ALT.
You are invited by our friends at Cambridge University to a talk by our Chairman Prof. James Campbell on Monday, 12 May @ 6 pm (BST) online or in-person for the grand finale to of this academic year's talks: 

Studying Water and Architecture - Does Infrastructure belong in Architectural History?

The talk will be given by Prof James Campbell (University of Cambridge) who will need little introduction to most of you, not least because he has been the incredibly generous host and sponsor of our events since their foundation in 2019!

But for those who don't yet know James, he is an architect and architectural historian. He co-founded the MSt in Building History with English Heritage, as well as created the new Apprenticeship in Architecture programme at the university. He is Chair of the Construction History Society and has written award-winning books on the history of brick, the staircase and the library, amongst others. His talk on Monday will present some of his latest research, which forms part of his upcoming book, Water  and Civilisation, which is due for completion in 2025. 

 As ever, our in-person lecture will take place at 6 pm in the beautiful Old Hall in Queens' College, Cambridge and will be followed by a drinks reception there. People can also join online via Teams webinar. The lecture is free and open to everyone. 

To register for online attendance via Teams, https://events.teams.microsoft.com/event/4c588f63-5717-4fa8-9659-50c3bb7f8592@49a50445-bdfa-4b79-ade3-547b4f3986e9

This expertise was the reason that in 1861 he was called in to help determine the cause of the collapse of the spire of Chichester Cathedral that had occurred during its restoration. Willis was very careful, however, not to voice any structural opinion, leaving that to professional engineers.3/4
