This rectangular three-storey tower house has seen centuries of ownership changes and architectural modifications, yet remains occupied to this day. Built with projecting rectangular towers at its east and west angles, each containing newel stairs, the castle represents a typical example of Irish fortified domestic architecture.

The castle's recorded history stretches back to at least 1640, when Lord Netterville of Ballygarth owned the entire parish, comprising 348 acres at Ballygarth and Corballis. According to the Civil Survey of 1654-6, his property included 'one castle, a house and some cabins', suggesting a small settlement had grown around the fortification. After the Restoration of 1660, ownership passed to the Pepper family, who would retain the property for over three centuries, well into the late twentieth century.

The building we see today reflects layers of architectural intervention across multiple periods. The original medieval tower house was modernised, likely during the mid-nineteenth century, whilst maintaining its defensive character. In 1782, a Georgian wing was added to the northeast, bringing fashionable domestic comforts to the ancient stronghold. The early nineteenth century saw the construction of a narrow entrance block that cleverly connected these two distinct architectural periods, creating a cohesive, if eclectic, whole that continues to serve as a private residence.
