Moated site, Lisboy, Co. Roscommon
Situated on a low east-west ridge in Lisboy, County Roscommon, this medieval moated site presents a fascinating glimpse into Ireland's defensive rural settlements.
Moated site, Lisboy, Co. Roscommon
The site consists of a roughly rectangular grassy enclosure measuring approximately 37.5 metres from north to south and varying between 23 to 27 metres from east to west. What makes this location particularly intriguing is its well-preserved earthwork defences; a substantial earthen bank defines the perimeter, with the southern portion cleverly incorporated into an existing field boundary.
The defensive features of this site reveal considerable medieval engineering skill. The western bank stands particularly prominent, measuring 5 metres wide with an internal height of up to 1 metre and an impressive external height of 1.6 metres. The eastern and northern edges are marked by scarps of 0.7 and 1.2 metres respectively. Surrounding the main enclosure on three sides (west, north and east), a moat system adds another layer of defence. These moats vary in width from 6.6 to 8.4 metres at the top, narrowing to about 5 metres at the base, with depths ranging from a shallow 0.1 metres at the northeast corner to a more formidable 1.55 metres on the western side.
Archaeological evidence suggests this wasn’t a simple defensive structure; fragments of outer banks remain visible on the northern and eastern sides, hinting at a more complex, multi-layered defensive system. The northern outer bank measures 4.6 metres wide with varying heights, whilst the eastern outer bank extends 5.7 metres in width. These remnants indicate that the original fortification was likely even more substantial than what survives today, representing an important example of medieval rural settlement patterns in County Roscommon.
