This is the motte of Kilsheelan, a Norman earthwork castle that has stood guard over this strategic river crossing for more than 800 years. The manor here was granted to William de Burgh by Henry II sometime during his reign from 1154 to 1189, suggesting the motte was likely constructed in the late twelfth century as part of the Norman consolidation of power in Ireland.

The motte itself is a compact but imposing structure, measuring approximately 7.7 metres across at its crest and standing about 6 metres high. Its grass covered slopes are steepest on the south and west sides, whilst the northern and eastern sections show signs of slippage over the centuries. Historical records mention an accompanying bailey; a fortified courtyard that would have contained buildings for the garrison and storage; though no trace of this or any other defensive earthworks survive today. Low stone walls now enclose the north and west sides of the mound, likely a much later addition to the original earthen structure.

The motte has undergone some curious modifications in modern times. In 1946, a grotto was carved into the northwest face, with builders excavating an area 8 metres by 5 metres and 3.4 metres deep to accommodate this religious shrine. Additionally, there’s a small hollow on the southeast section of the motte’s summit, measuring roughly 4.4 metres north to south, 6.1 metres east to west, and a metre deep; though its purpose remains unclear. Despite these alterations, the motte remains a well maintained example of Norman military architecture, continuing its silent watch over the River Suir just as it has done since the days of Henry II.
