The Round Tower remains the dominant monument of the monastic site. Visible across the surrounding countryside, it acted as a landmark within the urban landscape and emphasised the centrality of the church enclosure in the life of the town #IHTA #MapMonday

The boundaries of monastic Kells were marked by monumental sculpture. The High Crosses stood at key points around the precinct and helped define sacred space. They served as visual markers for residents, travellers and pilgrims moving through the settlement #IHTA #MapMonday

Unlike many medieval towns which developed around markets or castles, Kells grew around a religious foundation. The monastery acted as a centre of worship, learning, administration and exchange, which attracted people to settle around its precinct and created the nucleus of an urban community #IHTA

According to tradition, St Columba founded a monastery in the 6th cent. Significantly, the monastery occupied an earlier enclosed site whose boundaries continued to influence the layout and curved streets of the later town #IHTA #MapMonday

Kells derives from the Irish Ceanannas, a name possibly connected with an earlier royal fort or "head fort" (ceann lios). Long before it became a medieval town, the site was an important secular & ecclesiastical centre whose elevated position helped shape later settlement patterns. #IHTA #MapMonday

By the late 13th cent. Fethard was prosperous enough to seek royal funding to enclose the town. A murage grant of 1292 raised money through taxes on goods sold in the town, including wine, hides, timber, fish and grain. The walls enclosed an oval area of c. 7.5 hectares and stretched for c. 1.1km.

By the 13th cent. Kilkenny was enclosed by one of Ireland's most substantial town wall systems. The walls enclosed c. 28 hectares linking directly with the castle defences. Seven gates controlled movement through the town, including St Patrick's Gate, Walkin's Gate and St James's Gate. #IHTA

In c. 1173 the Anglo-Normans chose a different hill, 750 m S. of St Canice's to establish Kilkenny Castle. The castle controlled a bridge crossing, river traffic and major routeways. Its location created a new focus for settlement and marked the southern anchor the Anglo-Norman Hightown #IHTA

Viewed together, St Mary's, the College, Myrtle Grove, the North Gate and the town walls reveal how Youghal evolved over centuries. The northern end of the town became a powerful mix of defence, religion and learning, helping make Youghal one of Ireland's most distinctive medieval port towns 9/10

Just north-east of St Mary's stands Myrtle Grove. Probably built in the 15th cent. & likely associated with a priest of St Mary's, it formed part of the wider collegiate and ecclesiastical landscape that developed around the church. Later tradition linked the house with Sir Walter Raleigh 8/10

One of Youghal's most famous landmarks, the Clock Gate Tower, stands on the site of the town's principal southern gateway. Before the present structure was built in 1777, this was the location of a medieval gate known as Trinity Castle and, earlier still, the main entrance to the walled town 7/10

In 1464 Thomas FitzGerald, Earl of Desmond, founded Our Lady's College at Youghal and elevated St Mary's to collegiate status. The foundation supported a warden, eight fellows and eight choristers, creating one of the most important ecclesiastical institutions in late medieval Munster #IHTA 6/10
