The Civil Survey of 1654-6 recorded that ‘there standeth a stumpe of a Castle’ in the area, suggesting that even by the mid-17th century, the structure was already in ruins. Today, no trace of this castle remains visible at ground level, its stones having apparently met a practical fate.

According to family tradition, when the present Monaquill House was built in the nineteenth century, stone from both the old castle and an earlier house on the site was incorporated into the new construction. This practice of recycling building materials was common throughout Ireland, where good quality cut stone was valuable and often reused in successive buildings. Despite this oral history, no early stonework can be identified in the current house, its surrounding walls, or the farm buildings nearby.

The site sits on level ground, though the exact location of the castle remains uncertain. While family memory places it near the house, the complete absence of any physical remains makes it impossible to verify this claim. The Archaeological Inventory notes that thorough examination has revealed no medieval masonry in any of the standing structures, leaving only documentary evidence and local tradition to mark where this castle once stood.
