Greinburg Castle was built between 1488 and 1495 by Heinrich and Siegmund Prüschenk with the imperial approval of Emperor Friedrich III. In 1533 Johann Leble (Löbl), acquired the castle. Under him the building received most of its present day form. In 1621 the castle was sold to the Earl Leonhard Helfrich of Meggau, who carried out basic changes. A three storeyed, columned arcade became the main feature for the appearance of the inner courtyard. Furthermore, under Meggau the Sala terrena (so-called stone theatre) was installed. In 1625 the “Rittersaal”, the Hall of Knights, and an adjoining chapel in the south west tower were redecorated.
The Dukes of Saxe-Coburg and Gotha have been owners of the Castle only since 1822. The building, which comprises four wings, houses the Coburg Rooms, which are the official rooms of the ducal family, as well as the Upper Austrian shipping museum.
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.
