Went to see the Ruthven Cross on a recent visit to #Dumfries & Galloway. It didn’t disappoint. Wondering if similar monuments were ever made in wood.

Interesting. I wonder if it was rescued when the painted ceiling was saved.

Really worth a visit. If travelling by car there is a small car park nearby in the BFT Corehead and Ericstane estate. The wood pasture is on the west side of the road just a little way before the car park. Be aware there are often cattle grazing there.

Detached from its building but still looking fab, this early 16th-century door and doorway from Ipswich has a few features stylistically typical for that era, including vertical moulded fillets of wood hiding the joints of the timber boards on its outer face. From v&a. #ADoorAbleThursday
Timber door with ogee-headed wicket (smaller doorway through its fabric), set within massive, neatly dressed doorway, also of timber. The information panel by it reads:

DOOR AND DOOR FRAME
About 1500-30
The survival of this doorway is due in part to the robust construction, with thick broad planks strengthened by carved uprights and large iron nails. The door comes from a fine timber-framed house in Ipswich.

England, Ipswich
