Moated site, Clashduff, Co. Tipperary
On reclaimed grassland in the uplands of County Tipperary South, the remains of a medieval moated site at Clashduff offer a glimpse into Ireland's defensive past.
Moated site, Clashduff, Co. Tipperary
The site occupies flat, elevated ground with commanding views in all directions; a strategic position that would have been carefully chosen by its medieval builders. Today, all that remains visible are low, undulating earthworks that trace out a D-shaped enclosure measuring approximately 40 metres north to south and 35 metres east to west. The original moat, which would have provided the primary defence for whatever structure stood here, has long since been filled in and now appears only as a cropmark, roughly 3 metres wide with an external depth of about 0.2 metres.
Historical maps reveal how dramatically this site has changed over the past two centuries. The first Ordnance Survey map from 1840 depicts it as a square-shaped area with what appears to be a building at its centre, marked as reference TS049-045001. Field boundaries cut through the site at both the northern and southern ends during this period, suggesting the monument had already lost its significance as a discrete defensive structure. By the time the 1903 Ordnance Survey was produced, these field boundaries had been removed, and it seems likely that the moated site was substantially levelled during this agricultural reorganisation between 1840 and 1905.
The site’s relationship with its landscape provides additional context for understanding its original purpose. A stream runs to the west, with a fish pond located just 150 metres away and another enclosure 400 metres distant in the same direction. These water features and neighbouring earthworks suggest this was once part of a more extensive medieval landscape, possibly associated with a manor or small settlement. Aerial photography from the mid-20th century, particularly photograph ASIAP (26)14-18, clearly shows the D-shaped cropmark of the levelled moat, proving that even when earthworks are barely visible at ground level, the archaeological footprint of these medieval sites endures beneath the soil.
