Keiss Castle

It stands on sheer cliffs overlooking Sinclair's Bay, less than one mile north of the village of Keiss.

[2] The castle was constructed as a Z-plan tower house with 4 floors plus an attic and a vaulted basement.

The castle was built possibly on the site of an earlier fort in the late 16th or early 17th century by George Sinclair, 5th Earl of Caithness (1582-1643).

It seems the castle was in existence in 1623 when James VI commissioned Sir Robert Gordon to enter Caithness with an armed force.

The estate was purchased by Sir William Sinclair, 2nd Baronet of Dunbeath early in the 18th century and in 1752 Keiss became his family seat.
