Moated site, Coolnagun, Co. Westmeath
This square earthwork, measuring 35 metres on each side, dates back to medieval times when such fortified homesteads dotted the Irish landscape. The site appears on the 1837 Ordnance Survey map as a small square field with a boundary running through its southern section, suggesting it had already fallen out of use by the 19th century.
The monument consists of an earth and stone bank, varying in width from 3.4 to 10 metres, which originally enclosed the entire square area. Outside this bank runs a defensive ditch or fosse, best preserved on the eastern side where it reaches depths of up to 2 metres. The main entrance, a causeway 5.2 metres wide, breaks through the northern defences slightly off-centre to the east. The northeastern corner shows particularly interesting construction; the bank here has a deliberately raised, rounded profile that extends along the northern and eastern sides, with sharp, well-defined corners that speak to careful medieval engineering.
Today, the southern side tells a different story of decay and reuse. Here the bank has been reduced to little more than a scarp, and the protective fosse is barely visible, having been incorporated into old field boundaries that extend east and west from the monument. The interior slopes gently from northeast to southwest, and while time has softened many of the site’s defensive features, the overall footprint remains clear enough to understand how these moated sites once functioned as defended farmsteads for Anglo-Norman settlers or wealthy Irish families during the medieval period.
