The ruined Augustinian Abbey that is sited in the grounds was built in 1128 at the order of King David I of Scotland. It has been the site of many royal coronations and marriage ceremonies. The roof of the abbey collapsed in the 18th century, leaving it as it currently stands, a ruin. The Abbey was adapted as a Chapel for the Order of the Thistle by King James VII, but was subsequently destroyed by a mob. In 1691 the then-new Kirk of the Canongate replaced the Abbey as the local parish church, where today the Queen attends services when in residence at the Palace.

The abbey was founded in 1128 and rebuilt about 1220. The ruins of the nave are impressive examples of the bold, imaginative work of the period. The Palace of Holyroodhouse, which shouldered the abbey aside, comprises an early 16th-century wing and a 17th-century quadrangle court and facing wing. It is the sovereign’s official residence in Scotland.
