Rincolisky Castle, also known as White Hall, County Cork visited in August 1986.
It had an entrance at first floor level and another underneath it. One X shaped loop on the ground floor. The east wall over the lower door was corbelled out by approx a foot to create enough room for the stairs.
Vault as in Kilcoe over the first floor with “attic” space. Garderobe Shute exits at first floor level on the north wall around the corner from the entrance. Entrance to it was on first floor. A straight mural stairs turned into a spiral into the second floor.
There was nothing above second floor level, except a grass top
