Château de Quintin was mentioned as 'castellum novum' in 1202 and it was probably a fortified manor built in the late 1100s by Alain de Penthièvre. Geoffroy I Boterel built the first actual castle in the middle 1200s. it consisted of a moat, four gates, curtain walls and towers. The castle was badly damaged in the Wars of Religion (1590s).
The next castle was built as a living residence in 1643 and restored in 1785-1790. During the Great Revolution Château de Quintin was used as a prison. Since 1935 it has been owned by Bagneux family.
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.
