Church of St Mary on the Rock

The Church of St Mary on the Rock or St Mary's Collegiate Church, was a secular college of priests based on the seaward side of St Andrews Cathedral, St Andrews, just beyond the precinct walls. It is known by a variety of other names, such as St Mary of the Culdees, Kirkheugh and Church of St Mary of Kilrymont.

Although not founded as a collegiate church until the 1240s, Scotland's first, it represented a corporate continuation of the association of clergy known as the Culdees or Céli Dé, "vassals of God". The church lasted for several centuries, but did not long outlast the Scottish Reformation, and today little of the original structure has survived.
