Moated site, Caldrymoran,Lisboy, Co. Roscommon
First recorded on the 1837 Ordnance Survey map as a circular enclosure within a rectangular boundary, this grass-covered site measures approximately 31 metres north to south and 29 metres east to west. The rectangular area is defined by distinct features: an earthen bank along its northern edge that rises about 45 centimetres from the interior, the modern townland boundary with Lisboy to the east, a scarp up to 75 centimetres high on the southern side, and what appear to be old fosses or defensive moats along the western and northern perimeters.
The moats themselves are substantial features, varying between 3.3 and 5.3 metres wide at the top, with a consistent base width of 3.3 metres and a depth of roughly 60 centimetres. The northern earthen bank stretches 3.8 metres wide and maintains a fairly uniform height of about 40 centimetres when viewed from outside the enclosure. These defensive characteristics suggest the site may have been a rath, one of the thousands of early medieval ringforts that dot the Irish landscape, typically dating from the early Christian period between 500 and 1200 AD.
What makes this particular site especially interesting is its dual nature; the original 19th-century surveyors noted both circular and rectangular elements, a somewhat unusual combination for Irish earthworks. Whilst many raths are circular or roughly circular in plan, this example seems to incorporate both forms, possibly indicating different phases of construction or use. The presence of water-filled fosses or moats also sets it apart from simpler earthwork enclosures, suggesting this may have been a site of some local importance, perhaps the homestead of a prosperous farming family or minor nobility during the medieval period.
