Lucens Castle's strategic location allowed it to control the Broye valley, which was an important transit corridor. Starting in the Middle Ages and until 1536 it was a residence of the Bishop of Lausanne and served to control the Bishop's land in the Broye valley. During the 12th century, the castle was repeatedly destroyed and rebuilt. In 1476, it was destroyed by the Swiss Confederation. In 1536 the valley and the surrounding territory were conquered by Bern. It became the seat of a Bernese bailiwick at the same time. In 1542, the vogt of Moudon moved into the castle.
The castle was enlarged between 1579–86 and served as an arsenal and fortress on the border to Fribourg. In 1798, the Bernese were forced out and the Canton of Léman was formed. Shortly thereafter, the castle became the property of Canton, who sold it 1801 to private individuals. In 1925, it was converted into a Swiss Reformed institute for girls. Between 1965-70, it was the seat of the Conan Doyle Foundation, and is now in private hands.
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.
