The Burg Liebau is the ruin of a spur castle on a flat rock spur on the right flank of the Elster. The castle was first mentioned in a document in 1327. In the 14th century exchanged Plauen Vogt Heinrich the Elder including the castle with the Wettiners and 1441 the castle was owned by the Dölau, of which the castle from 1500 to 1550 graduated like in Renaissance style was rebuilt.
In 1640 the castle was sacked by Swedish mercenaries and the stair tower was set on fire. The castle remained with its last owner Gottlob Christian von Doelau on Ruppertsgruen and his wife Sophia Christina geb. von der Planitz owned it until 1725, was then owned by Johanna Charlotte von Beust until 1742 and then fell into disrepair.
From 1995 to 1997 security work took place in cooperation with the State Office for Archeology and is now a ground monument .
The castle complex on an approximately triangular plateau measuring 50 by 30 meters probably consisted of a defensive and residential tower , the gate tower and a surrounding wall with battlements , further protected by two section trenches that were approx. 5 meters wide and 2 meters deep. The actual castle ruin has the dimensions of 20 to 25 meters. To the east, the complex was protected by a partially natural 20 to 25 meters wide and 5 to 6 meters deep neck ditch with a drawbridge.
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.
