Château de Saint-Malo was built between 1424 and 1690, first by Jean V, the Duke of Brittany. The Duke Francois II built the first tower in 1475. In 1590 during the Wars of Religion the castle was occupied by local people, who wanted to prevent local governor to gave the city to Protestant king Henry IV.
The château was modified in the 17th century according the design of famous fortress architect Sebastian Vauban. In the 19th century it functioned as barracks. Today it is a museum, covering a number of themes including the long maritime history of St-Malo, 19th century writers of which Chateaubriand is the most well known, WWII occupation and the destruction and reconstruction of the town.
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.
