The structure dates back to the medieval period when such fortified buildings were essential for controlling territory and protecting local populations. Its location in this part of Kilkenny speaks to the strategic importance of the area during centuries of Norman and Anglo-Irish rule.

The castle’s architecture follows the typical pattern of Irish tower houses from the period, with thick stone walls designed to withstand both siege and the harsh Irish weather. These defensive structures were often built by wealthy landowners who needed to protect their estates whilst also displaying their status and power. The name Oldcourt itself suggests this was once a place of local administration and justice, where the lord would have held court and managed the surrounding lands.

Today, the castle stands as a monument to Ireland’s complex medieval past, when the countryside was dotted with hundreds of similar fortifications. Each one tells a story of the families who built them, the communities they protected, and the turbulent times they weathered. While many such castles have crumbled or been demolished over the centuries, survivors like this one in Oldcourt offer visitors a tangible connection to the people who once called these stone walls home.
