This circular earthen platform, measuring roughly 23 metres across and standing about 2.5 metres high, is actually a castle motte; a type of Norman defensive structure that would have originally supported a wooden tower or keep at its summit. Though time has worn away any visible structures that once crowned this artificial hill, traces of the surrounding fosse, or defensive ditch, can still be spotted by keen observers.

The motte represents a fascinating piece of Ireland’s Norman heritage, dating back to the period following the Anglo-Norman invasion of 1169. These earthwork castles were quick to construct and provided the new arrivals with strategic strongholds from which to control the surrounding territory. The choice of location next to the existing church at Clonenagh was no accident; Norman lords often built their fortifications near established religious sites, both to assert their authority over the local population and to benefit from the existing infrastructure and community.

Today, while the site might appear as little more than a grass-covered mound to the casual passer-by, it serves as a tangible link to the turbulent medieval period when control of the Irish landscape was contested and reshaped. The motte’s proximity to the church and graveyard creates an intriguing historical landscape where centuries of Irish history, from early Christian times through the Norman conquest and beyond, exist side by side in this quiet corner of Laois.
