Schloss Waldreichs was first documented in 1258. Around 1400, Kaspar and Bernhard von Waldreichs are mentioned as feudal lords. After its destruction by an executionary army of the estates in 1446–1448, it was rebuilt as a fortress around 1450 under Hans Harrasser. The present-day ruin in the east wing, the chapel, and the eastern tower date from this period. In 1460, it was enfeoffed to Vinzenz Stodoligk. From 1519–1536, it was united with the Lordship of Ottenstein. Between 1530–1534, it was converted into a moated castle under Eustach Stodoligk. From 1533, it was a free property. In 1536, the complex passed to the Barons of Altena, who expanded it with a zwinger and a manor farm. After its conquest and plundering by imperial troops, the complex was rebuilt again and subsequently changed owners frequently. When it passed to Heinrich von Pereira-Arnstein in 1815, it was united with the Lordship of Wetzlas.

Please do not deface it!!! Below Hartenstein Castle lies the Gudenus Cave, which was carved out of the riverbank and inhabited by Neanderthals during the Stone Age. Traces of settlement dating back almost 100,000 years were discovered there, including hand axes and other tools. Due to historical preservation, the bridge could no longer be rebuilt unless the cave was sealed.

The entrance to the cave is overgrown, which is a pity.

We read somewhere that this dam would no longer be approved today. Nevertheless, the lake fits well into the landscape. It has a strange, branched shape!
