Mingarry Castle was considered a strategically important site in terms of communication with overseas areas and as an entranceway to the Sound of Mull. Originally built in the 13th century for the Clan MacDonald of Ardnamurchan, the castle has had many different occupants. King James IV of Scotland used it as a stronghold for fighting off Clan Donald in the late 15th century. In 1515 the castle was besieged by the Clan MacDonald of Lochalsh and again two years later when they finally took the castle.
In 1588 the chief of the Clan MacLean of Duart resided there after capturing the chief of the Clan MacIan of Ardnamurchan. In 1588, one of the ships of the Spanish Armada, named the San Juan de Sicilia, landed on Mull and MacLean of Duart used troops from the ship to aid him in his warring against the MacDonalds of Clanranald and the MacIans of Ardnamurchan. On one occasion, a force from the ship besieged to the castle for three days before withdrawing.
Other occupants over the years included the Clan Campbell, the Earls of Argyll (in 1612), and Alasdair Colkitto MacDonald who fought the English Parliamentarians of Oliver Cromwell in 1644. The majority of the current building dates from the 17th century onwards. Mingarry is roughly hexagonal in shape with nine-foot-thick walls, thicker on the seaward side.
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.
