Oronsay Priory was a monastery of canons regular on the island of Oronsay. It was in existence by 1353, perhaps founded by John of Islay, Lord of the Isles. It was dedicated to St. Columba, and perhaps was a continuation or a re-activation of an older foundation. Very little is known about it because of the absence of records and its remoteness from the Scottish Lowlands, but on occasions some of the Priors of Oronsay come into the records.
The priory continued in operation until at least 1560, the year of the Scottish Reformation, with the last known prior, Robert Lamont, having been elected in 1555. The lands and property of the priory were given in commendam to Maol Choluim MacDubhthaich in 1561. They were later given to the Bishop of the Isles by King James VI of Scotland after his ascendancy to the throne in 1583. The ruins have been restored and are visible today.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
