When James VII was deposed in the Revolution of 1688, Ludovic Grant of Freuchie sided with William of Orange and garrisoned the castle with 200 of his own soldiers. Though lacking weapons they were well-provisioned and, when a force of 500 Jacobites (supporters of the exiled James) laid siege, the garrison were able to hold out until after the defeat of the main Jacobite force at Cromdale in May 1690. When the soldiers finally left they blew up the gatehouse to prevent reoccupation of the castle by the Jacobites. Large blocks of collapsed masonry are still visible beside the remains of the gatehouse. Parliament ordered £2,000 compensation to be paid to Grant, but no repairs were undertaken. Subsequent plundering of the stonework and other materials for re-use by locals further reduced the ruins, and the Grant Tower partially collapsed following a storm in 1715.
