Keiss Castle

Keiss Castle is a partially ruined castle in Caithness, Scotland. It stands on sheer cliffs overlooking Sinclair's Bay, less than one mile north of the village of Keiss. It is protected as a scheduled monument. The old castle was replaced by Keiss House around 1755. The castle was constructed as a Z-plan tower house with 4 floors plus an attic and a vaulted basement. It had a pair of corner towers at opposite angles of a square central block, the main tower being very narrow for its height with tall chimneystacks.
