In 1689, King James VII of the House of Stuart was declared to have to forfeit the throne, and the crown was offered to William of Orange, in the so-called "Glorious Revolution". The revolution also established Presbyterianism in Scotland, although the Highlands generally remained Roman Catholic and loyal to the Stuarts. A series of Jacobite risings followed, leading to an increased military presence in Scotland as government forces attempted to penetrate and subdue the Highlands. In 1714 while surveying fortifications for the government, the military engineer Lewis Petit made the only surviving drawing of Eilean Donan. The sketch-elevation and carefully drawn plan show a dilapidated castle, largely roofless but for a small building by the entrance.
