Located about 3 miles north of Wick, it is considered to be one of the earliest seats of Clan Sinclair. In its earliest incarnation, Castle Sinclair Girnigoe was known only as Castle Girnigoe. It was built by William Sinclair, the 2nd Earl of Caithness, sometime between 1476 and 1496. He died at the Battle of Flodden in 1513.
