Castle - ringwork, Clonlost, Co. Westmeath
Set within pastoral fields in County Westmeath, this intriguing earthwork represents a bivallate ringwork, a type of medieval fortification characterised by its double banks.
Castle - ringwork, Clonlost, Co. Westmeath
The monument appears on the 1913 Ordnance Survey map as a roughly circular enclosure measuring approximately 61 metres north to south and 60 metres east to west. Its distinctive double banks, though now weathered to scarps, still clearly define the site; the inner bank encircles a slightly raised oval area, whilst the outer counterscarp creates a wider circular perimeter that doesn’t quite match the inner ring’s alignment.
The fortification’s defensive layout becomes clearer upon closer inspection. Two gaps in the banks at the south-southeast mark the original entrance, with a curious radial bank cutting across the western sides of these openings, possibly part of a more complex gateway arrangement. Another radial bank appears at the north-northeast position. Between the two main banks, the intervening space shows evidence of old tree stumps, whilst a modern field boundary has been built against the outer scarp’s base from the east-northeast round to the south-southeast. The interior ground rises gently from the edges, with stones breaking through the surface here and there, and traces of what appears to be a medieval hut site can still be detected at the centre.
This ringwork sits just 50 metres west-northwest of another ringfort, suggesting this area held strategic importance during medieval times. The Archaeological Survey of Ireland has documented the site thoroughly, including detailed plans and profiles, and aerial photography from Digital Globe clearly shows the tree-lined earthwork’s distinctive double ring formation. Though time and farming have softened its military edges, the monument remains a remarkably intact example of Norman or Anglo-Norman defensive architecture in the Irish midlands.
