From this vantage point, visitors are rewarded with sweeping views across the Myross headland and out to the Atlantic Ocean. Though local tradition claims the castle was built in 1251, the architectural evidence suggests the ruins date from the 15th or 16th century, a period when tower houses were being constructed throughout Ireland as fortified residences for the Anglo-Norman and Gaelic nobility.

The castle once formed a substantial rectangular structure, measuring approximately 15 metres northwest to southeast and 8 metres northeast to southwest, as recorded on the Ordnance Survey map of 1902. Today, much of the building has been reduced to rubble, though several features remain to hint at its former grandeur. Part of the southwest wall's lower battered face still stands, its sloped design typical of defensive architecture meant to deflect projectiles and strengthen the base against undermining.

The most intact portion is the western corner, which rises to what would have been the first floor level. Here, the remains of two window embrasures are still visible; the ground floor window features double splaying, where the opening widens both internally and externally to maximise light whilst maintaining defensive capabilities. These architectural details, along with the castle's commanding position, speak to a time when controlling the landscape meant survival, and every stone served both domestic and military purposes.
