Dear Adrian:
There are quite a few Sinclair castles but the only one that carries the
name "Sinclair Castle" is near Wick in Caithness. It was, for it's time
(16th C.) , the modern addition to the older Girngoe Castle, the seat of the
Earls of Caithness.
FYI: other Sinclair Castles:
Rosslyn Castle, Dunbeath (still very habitable), Ravenscraig in Fife ( a
ruin) Thurso Castle, and several others.
