This late 16th or early 17th-century circular tower house rises five storeys high with an attic above, its roughly coursed rubble walls measuring between 2.4 and 3 metres thick. When the Civil Survey documented it between 1654 and 1656, the castle was described as “one old castle inhabited yett wanting repaire a broken bawne and the ruins of a stone house”, with Sir John Morres listed as its proprietor in 1640.

The castle’s defensive features reveal the turbulent times in which it was built. Visitors would have entered through a two-centred doorway on the west side, passing through a lobby watched over by a murder hole above, with a guardroom to the right and spiral stairs to the left. The ground floor, lit by three narrow slit windows, had a wooden ceiling supported on stone corbels, whilst the first floor above featured a barrel vault. A clever system of mural passages runs through the thick walls, connecting various chambers to garderobes in the southeast angle and providing access to defensive positions. The murder hole could be reached via a passage in the west wall at first-floor level, allowing defenders to attack anyone who breached the main entrance below.

The upper floors showcase the more comfortable domestic arrangements typical of tower houses from this period. The second floor boasts a finely cut stone fireplace in the west wall alongside a twin-light elliptical-headed window, with what was likely a kitchen area accessed through a mural passage in the north wall. Similar twin-light windows with ogee heads illuminate the third floor, where another fireplace once warmed the chamber. Throughout the castle, mason’s marks in the form of crosses and vertical lines can still be seen on doorway and fireplace jambs, whilst the punch dressing on window jambs confirms the late 16th or 17th-century date. Though the OS Letters from 1930 mention a bawn wall with corner towers and a late 17th-century house immediately south of the castle, no traces of these structures remain today.
