Moated site, Mountirvine, Co. Sligo
In the townland of Mountirvine, County Sligo, a medieval moated site sits quietly amidst marshy pasture, its earthworks barely distinguishable from the surrounding rushes.
Moated site, Mountirvine, Co. Sligo
This low, square platform measures roughly 21 by 22 metres and features the classic defensive elements of such sites: a central raised area surrounded by a water-filled ditch, or fosse, and an outer protective bank. The platform itself, now level and overgrown with rushes, rises just 0.6 metres above its surroundings, whilst the encircling fosse varies in width from 3 metres on the northeast side to nearly 5 metres on the southwest.
The site’s preservation varies considerably around its perimeter. The southwestern side remains the most intact, where visitors can still clearly trace the defensive earthworks; a low outer bank, measuring between 3 and 3.5 metres wide, rises about half a metre above the surrounding ground. Moving clockwise, the northwestern and northeastern sides show increasing degradation, with some sections reduced to mere grassy cropmarks. The eastern corner and southeastern side have fared worst, where centuries of weathering and waterlogging have rendered the defensive features almost indistinguishable from the marshy ground. A faint grassy mark, approximately 2 metres wide, running along portions of the scarp may indicate where an inner bank once stood, adding an extra layer of defence to this rural stronghold.
A stony causeway, measuring just over 2 metres wide, provides access to the platform from the gently rising ground to the south, cutting through the outer bank and crossing the fosse on the southwestern side. This same causeway continues across the platform and exits through the northeastern defences, suggesting it may be a later addition, perhaps created when the site’s defensive purpose had long been abandoned. Today, a modern field boundary and drainage ditch bisect the monument on a northwest to southeast axis, whilst a 12-metre strip of wet, flat ground separates the entire moated complex from the drier land beyond, preserving this medieval earthwork as an island of history in the Sligo landscape.
