Moated site, Knockbeg West, Co. Sligo
On the south bank of the Owenmore River in Knockbeg West, County Sligo, lies a fascinating medieval moated site that offers a glimpse into Ireland's defensive architectural past.
Moated site, Knockbeg West, Co. Sligo
The site occupies level pasture ground, with the river providing natural protection to the north whilst undulating terrain rises to the south, now heavily altered by quarrying activities some 50 metres away. The rectangular enclosure measures 29 metres north to south and 53 metres east to west, defended by an earthen bank and external water-filled ditch, or fosse, on three sides. The bank, now grass-covered and compact, stands about a metre high on its outer face, whilst the fosse, though its outer edge has softened over time, remains clearly visible thanks to the distinctive growth of irises that trace its course.
The most striking feature within the enclosure is a circular, flat-topped mound positioned in the southwest quadrant. Rising 1.8 metres at its highest point, this mound spans 19 metres in diameter with gently sloping sides and a level summit of about 10 metres across, marked by a slight central depression. The enclosure’s single entrance, a narrow 2.3-metre-wide gap with a causeway crossing the fosse, opens towards the western end of the south side. To the north, where one might expect similar defensive earthworks, the site instead incorporates a natural break in slope; a broad, low stony scarp that extends beyond the enclosure’s boundaries and appears to have been adapted as a field boundary, though dense riverside vegetation now makes detailed examination difficult.
This moated site doesn’t stand alone in the landscape but forms part of a cluster of medieval earthworks. Another moated site sits just 20 metres to the west, whilst a possible rectangular enclosure lies an equal distance to the east, suggesting this area held considerable importance during the medieval period. The eastern side shows signs of later agricultural modification, with the bank levelled to a gentle rise and the fosse filled to create merely a shallow depression. Today, the interior is overtaken by long grass, rushes and irises, whilst the northern edge remains shrouded in a thicket of bushes that line the riverbank, preserving something of the defensive isolation these sites once commanded.
