In 1100, a nobleman named Heinrich named himself after the old Clingenburg (castle). He belonged to the noble family of Reginbodo. The Clingengurg castle was built around 1160-1170 by Conradus Colbo, who was cup-bearer to Emperor Friedrich Barbarossa.
About 1250, the Bickenbach noble family moved into the castle; the Bickenbachs later held many influential offices in the Holy Roman Empire and many a time turned up in Imperial politics as brokers.
After the Bickenbachs died out in 1500, the town, castle and lordly domain passed to the Archbishop of Mainz. Clingenburg castle was destroyed by the French in the late 17th century and never rebuilt. It remained a ruin.
In the 20th century Clingenburg was opened up to tourism with a restaurant and a lookout platform affording visitors a view over the old town and the Main valley. Since 1994, the Clingenburg-Festspiele have been taking place, drawing many visitors each year with changing plays and musicals.
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.
