A stream runs 60 metres to the north of this unusual fortification, which likely dates to the 16th century based on its architectural features, including gun loops, an armorial plaque, and distinctive punch dressing. The castle’s history is well documented; William Faninge held it as proprietor in 1640, when it was described as a ‘good little castle with a good thatcht house & some cabbins’. Earlier records reveal that a house belonging to William Fanyng, gentleman, was deliberately burned here in 1555, whilst Edmund Fanning of Farranrory appears in documents from 1579.

The tower house itself is circular in plan, with an internal diameter of 5.3 metres and walls 2.35 metres thick, surviving to three storeys though only the lower walls of the top floor remain intact. Its construction from roughly coursed limestone rubble features a slight base batter and a pointed doorway in the northwest face, complete with limestone jambs designed to receive a yett (iron gate) and a yett hole in the apex. Above the doorway sits a blank plaque, likely intended for armorial decoration. The defensive nature of the structure is evident throughout; immediately inside the main entrance, a lobby area was protected by an overhead murder hole, whilst a cruciform gun loop with fine foliate decoration faces the entrance. The ground floor, accessed through an ante-chamber, is lit by three windows set into large segmental arched embrasures, each flanked by gun loops. These windows feature round headed openings with punch dressed limestone jambs, and the southeast window’s spandrels are decorated with stiff leaf foliage.

Later modifications tell of the castle’s evolution from defensive structure to domestic dwelling. The remains of a two storey farmhouse, possibly dating to the 17th century, are attached to the west face of the tower. When this addition was made, the original doorway was blocked up and a slit opening inserted, with new access created from the ground floor of the farmhouse. The tower now stands within a disused farmyard, surrounded by ruined outhouses to the north and south, though no traces of a bawn wall remain. Unfortunately, the structure is in poor condition; trees grow from the wall tops and structural cracks are visible in the north and south faces. Despite this deterioration, evidence of the building’s craftsmanship survives, including wicker centring marks on the undersides of the segmental arched embrasures and a fine vault over the first floor, offering glimpses of the skilled construction techniques employed by its 16th century builders.
