The Château de Lassay is a 15th-century castle in Lassay-les-Châteaux. The first mention of a castrum in Lassay dates back to the 12th century. Owned by Charles de Vendôme at the beginning of the 15th century, the castle was destroyed by French troops as Charles de Vendôme supported the English during the Hundred Years War.
In 1458, the French king Charles VII allowed the son of Charles de Vendôme, Jean II, to rebuild a castle. The new castle was achieved within one year. The barbican was built in 1497-1498.
Since then, the castle has been left mainly intact and the original 15th-century architecture preserved by the different owners of the castle.
The castle is listed as a Monument historique since 1862. It is open for visiting from April to September.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
