An unsigned map from 1707 reveals that this site once hosted an impressive three-storey tower house with an attached two-storey dwelling, accompanied by three modest single-storey cottages. The castle, marked as ‘Ca Rs’ on Taylor’s 1783 map of County Kildare, served as one of several fortifications built to protect the Pale, the medieval English-controlled territory surrounding Dublin.

Historical records suggest this castle played a crucial role in the defensive network that safeguarded English settlers from raids originating beyond the Pale’s boundaries. The tower house would have provided both a military strongpoint and a residence for local nobility or their representatives, whilst the smaller attached buildings likely housed servants, soldiers, or agricultural workers essential to the castle’s daily operations.

Today, visitors to Flemingstown North will find only grass-covered foundations marking where this once-formidable structure stood. The rectangular outline of the building remains visible to those who know where to look, offering a tangible connection to Ireland’s complex medieval past when the landscape was divided between Gaelic Irish territories and English-controlled lands. Though the stones have long since been carried away for other building projects, the site continues to tell its story through old maps and the subtle impressions left in the earth.
