Crossraguel was sacked in 1307 by the army of Edward I. It was rebuilt on a larger scale and remained a monastery until 1560, when the Reformation ended monastic institutions in Scotland. However, the few remaining monks were allowed to live out their time there until the last monk died in 1601. Some of the stone has been removed for local construction, but the Abbey ruins remain some of the most complete of any medieval religious house to survive in Scotland. Like Paisley Abbey, Crossraguel was of the Order of Cluny whose mission was to encourage pilgrimage. It is no accident then that Crossraguel is half-way between Paisley and Whithorn on the Ayrshire pilgrims' trail to the shrine of St Ninian in The Machars of Galloway. The site is looked after by Historic Environment Scotland as a scheduled monument and is open to the public with an entrance charge.
