Waldmannshausen Castle  Waldmannshausen Castle () is a water castle built from 1486 to 1488 by Thebus of Waldmannshausen in the village of Elbgrund in the municipality of Elbtal) in the county of Limburg-Weilburg in the German state of Hesse. It is located about 18 kilometres north of the town of Limburg an der Lahn. The castle was once a single unit with the neighbouring estate of Waldmannshausen. On the land of the estate is another, ruined, water castle, the Alte Burg ("Old Castle"). The property is on the edge of the municipality on the road to Frickhofen. The castle and its associated "schloss", built in 1790, have been used as a "Schullandheim" - a country educational facility used to enhance normal schools - since 1935. The castle is owned by "Schullandheim Burg Waldmannshausen;; with its headquarters in Westphalian Hagen. The von Waldmannshausen family is first recorded in 1136. From the "Walpodes of Waltmannshausen" branched early on the other Walpode/Waldbotten lines, including Waldbott of Bassenheim. The builder of the present castle was Thebus (also: Debus = Matthäus) of Waldmannshausen, who died in 1506. He was the son of Gerard of Waldmannshausen and, during the 1480s, was a vassal of the counts of Nassau-Dillenburg. In the 17th century the castle had become a ruin. In 1786 it was repaired by Christian Heinrich of Erath and, in 1790, expanded with a "schloss" next to the castle. After 1835, it changed hands more often and, in 1935, was acquired by the "Schullandheim" society of the Westphalian city of Hagen. Today, castle and "schloss" are listed buildings and also have protected status in the event of war under the Hague Convention. The "new castle" was built in 1486 as a Late Gothic water castle, initially without cellars. It is a three-storey, Late Gothic stone edifice with a steep, gabled roof. On two opposite corners there are round towers with conical roofs and, in the centre of the front, longer side, is a staircase tower. The moats have been levelled.
