Huntingtower was originally the early 15th century House of Ruthven, a stone rectangular keep founded by the Ruthven family. Its three storeys and garret, are crowned by a corbelled-out parapet and when a western L-plan tower house was built in late 15th or 16th century, the keep was also remodelled. Almost but not quite touching, the main block of the tower house is of four storeys and garret, the wing is a storey higher and both have a corbelled-out parapet. The two towers flanked a strong walled barmkin and in the late 16th century, a great hall was attached to the north side of the keep. In 1582, the castle was the scene of the 'Ruthven Raid' when the young King James VI was held here against his will. But following the 'Gowrie Conspiracy' of 1600, Ruthven was granted to William Murray, earl of Dysart and renamed Huntingtower. In 1663, after the castle passed to the Murrays of Tullibardine, the two towers were linked by a one bay block. 5 miles south-east is Kinfauns Castle.
