Lochindorb Castle is a former stronghold of the Clan Comyn and is built on what now is said to be an artificially created island. The castle is first recorded during the Wars of Independence when Sir John ('the Black') Comyn died there in 1300. By 1455 the castle was in the hands of Archibald Douglas, Earl of Moray, The next year, after Douglas's defeat and death at Arkinholm, Lochindorb was again forfeited to the Crown and this time ordered to be slighted, the work of dismantling its defences being entrusted to the Thane of Cawdor. Since then, it has been left as a ruin.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
