The main structure consists of a rectangular four-storey tower house, measuring roughly 9.3 metres east to west and 7.25 metres north to south, with a later dwelling added to its southern wall. Low stone footings extending northward from the tower hint at additional structures that once stood here, though their exact purpose remains unclear. The castle’s history traces back to the Stapleton family before passing to the Percivals in the 17th century and later to the Freemans; it appears as a house on the Down Survey maps of 1655-6, suggesting it was still inhabited during that tumultuous period.

Today, only the western end of the tower survives to its full four-storey height, with short sections of the north and south walls still standing. A peculiar vertical gap runs nearly the full height of the west wall, topped by a brick arch near the gable apex; this appears to be where original windows on each floor were replaced with wider embrasures featuring brick jambs, though the sills and lintels have long since collapsed. One original feature that survives is a double-splayed slit window on the ground floor at the western end of the south wall, whilst a damaged fireplace occupies the northwest corner at second-floor level. The walls are crowned with tiered cornices at eaves level, matching those on the added house and suggesting they were built around the same time.

The attached dwelling, though missing a substantial section of its western wall, reveals intriguing domestic details. Its ground floor entrance sits at the northern end of the east wall, with a central fireplace in the south wall that’s lost its eastern side. A brick bread oven tucked into the southeast corner speaks to daily life in the castle, whilst rows of joist sockets in the walls mark where wooden floors once divided the interior spaces. Windows pierce the walls at various levels, including two flanking a fireplace in the south gable at attic level. Where the tower house meets this later addition, a curious curved recess with brick inclusions might be the remains of a circular stair tower, though its exact function remains debatable.
