The Tolštejn Castle (now reduced to ruins) was built in 1278 as part of the Zittau region's defense structure. George of Poděbrady ordered the castle to be seized shortly after the Hussite Wars and after many conflicts, the Tolštejn dominion was taken by 1471 by two Saxon princes, Ernest and Albrecht. During the Thirty Years War, the army of the Austrian Emperor occupied the castle. In 1607, the Swedish General Wrangel laid siege and burned down the castle.
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.
