Šlokenbeka Castle is a fortified manor and the only existing example of a fortified manor centre in Latvia. The construction was started by the Livonian Order before 1544. It was built in a trapeze-type yard, which was enclosed with stone walls and portholes. In 1772 the attic roofs were added to the building.
In the 17th century towers with portals and weathervanes were erected, but Šlokenbeka lost its defence function, being then adapted for domestic purposes. At the end of the 18th century new buildings were built and old buildings were renewed. New gate towers were added at the north and south walls. Between 1841 and 1845, a new manor house in classicist style was built at the north wall. In the 1930s Šlokenbeka lost some of its buildings. During Soviet times it housed the 5th road maintenance unit. Now it contains the Latvian Road Construction History Museum and a restaurant.
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.
