This impressive earthen mound rises about 8 metres high, with a flat summit measuring roughly 18 metres across and a base spanning nearly 34 metres in diameter. The conical structure, now overgrown with briars and thorn bushes, represents the remains of a Norman motte; a type of fortification introduced to Ireland following the Anglo-Norman invasion of the 12th century. The base of the mound shows clear signs of having been deliberately scarped, a defensive technique that would have made the steep sides even more difficult for attackers to scale.

The motte likely once supported a wooden tower or palisade at its summit, serving as both a defensive stronghold and a symbol of Norman authority in the region. Faint traces of earthworks can still be detected in the fields surrounding the base, possibly marking the location of a bailey; the enclosed courtyard that typically accompanied these fortifications and housed workshops, stables, and living quarters for the garrison. Just 110 metres to the northwest lie the ruins of a medieval church and graveyard, suggesting this was an important settlement site that continued to be significant long after the motte’s military purpose had ended.

The site’s historical importance was formally recognised when it was added to the Register of Historic Monuments in February 1975. Though the dense vegetation makes detailed examination challenging today, Killeshin Moat remains a striking reminder of the Norman conquest and the dramatic changes it brought to the Irish landscape. Its commanding position and substantial earthworks speak to a time when control of the countryside depended on strategically placed fortifications, each one a node in a network of Norman power that gradually extended across medieval Ireland.
