This tower-house, said to have been built in 1570 by an English soldier, Captain Browne, is badly ruined but is still of considerable interest. Rectangular and fairly small in ground plan, it was entered by a door in the north-west wall which has a draw bar socket and a murder-hole. To the left of the door was a stair to the next floor. There are two ground floor rooms, the larger with a semi-circular vault built on plank centring and the smaller with a pointed vault built on paired wicker mats. The smaller room, once thought to be a secure boat bay, may be just a storeroom (compare nearby Sketrick). There were two storeys above, but the upper parts are ruined. Part of the bawn wall survives to the south-west, cut into the hill.

This Lightship spent most of its previous working life at Blackwater Bank on the River Blackwater, Wexford. It was then sold in 1968 to Hammond Lane foundries in Dublin, before being saved to use as the cruise club HQ. The boat is registered as a national historic ship in the UK.
