Inchcolm Abbey

Inchcolm Abbey is a medieval abbey located on the island of Inchcolm in the Firth of Forth in Scotland. The Abbey, which is located at the centre of the island, was founded in the 12th century during the episcopate of Gregoir, Bishop of Dunkeld. Later tradition placed it even earlier, in the reign of King Alexander I of Scotland (1107–24), who probably had some involvement in the island; he was apparently washed ashore there after a shipwreck in 1123, and took shelter in a hermit's hovel.
The Abbey was first used as a priory by Augustinian canons regular, becoming a full abbey in 1235. The island was attacked by the English from 1296 onwards, and the Abbey was abandoned after the Scottish Reformation in 1560. It has since been used for defensive purposes, as it is situated in a strategically important position in the middle of the Firth of Forth. A medieval inscription carved above the Abbey's entrance reads "Stet domus haec donec fluctus formica marinos ebibat, et totum testudo perambulet orbem", or, "May this house stand until an ant drains the flowing sea, and a tortoise walks around the whole world".
Inchcolm Abbey has the most complete surviving remains of any Scottish monastic house. The cloisters, chapter house, warming house, and refectory are all complete, and most of the remaining claustral buildings survive in a largely complete state. The least well-preserved part of the complex is the monastic church. The ruins are cared for by Historic Environment Scotland, which also maintains a visitor centre near the landing pier (entrance charge; ferry from South Queensferry).
In July 1581 stones from the abbey were taken to Edinburgh to repair the Tolbooth.
Among the Abbots of Inchcolm was the 15th-century chronicler Walter Bower.
Inchcolm Antiphoner.
The Abbey gives its name to the 14th-century manuscript referred to as the Inchcolm Antiphoner. It contains one of the few remaining examples of Celtic Plainchant. Pages of the Antiphoner can be accessed online in facsimile from the University of Edinburgh.
The Antiphoner contains a substantial number of chants dedicated to Saint Columba. While these may derive from a variety of other monastic foundations with Columban associations, such as Oronsay Priory or Iona, Inchcolm is considered the most likely source of the manuscript's compilation, if not composition.
