Nyon Castle is first mentioned in 1272, but probably dates back to the Lords of Prangins. It was rebuilt by Ludwig I of Savoy. The rectangular building was built in a variety of building styles. In 1463, it was extensively rebuilt. Following the Swiss Confederation invasion of Vaud in 1530, the Bernese bailiff was at Nyon. In 1574-80 the castle was converted into the seat of the bailiff. It remained the seat of the bailiff and was renovated several times in the following centuries.
Today Nyon Castle is a museum.
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.
