Old Keiss Castle *
This ruined tower-house stands dramatically on the very edge of a sheer cliff falling to the sea below. Most of it survives to its full height of four-storeys and an attic, but one corner has fallen away completely, so that one can see the interior without going inside, which is unsafe.
The castle belonged originally to the Earls of Caithness, and later to two other branches of the Sinclair family. It was finally abandoned when the new Keiss Castle was built in 1755 (ND 355617).
