Dauchstein Castle

Beautiful view, and also very hidden,

The castle is called Burg Dauchstein, not Burg Binau and was probably once a customs post to collect the poor rivers and traders.

Dauchstein Castle near Binau in the Neckar-Odenwald district in Baden-Württemberg is said to have been built around 1030 as a customs castle for Neckar shipping. According to tradition, the road toll was collected with the help of a chain stretched across the Neckar, which was only lowered (dauch) after the required duty had been paid, hence the name Dauchstein. However, Ludwig Hildebrandt sees the etymological derivation Tahenstein/ Tugstein/ Duckstein/ Dauchstein, which is common today as tuff stone.
The hilltop castle is located in the southern Odenwald on the Neckar above the B 37 and is built on a slab of rock. It stands on a hill of calcareous tuff that was formed by a strong calcareous water source.
The origins of the castle are largely obscure. Around 1080, a Kuno von Tahenstein is mentioned (once) in a document, whose seat does not necessarily have to have been in Dauchenstein. Only at the beginning of the 14th century did further mentioning of documents appear. A piece of wood on the residential tower found by the local historian Ludwig Hildebrandt in 2004 was salvaged by the State Monuments Office and its striking time was dated to the winter of 1334/1335, which can be an indication of the time when the residential tower was built. Hildebrandt assumes that the castle was rebuilt at that time on the orders of the Counts Palatine, who then occupied Castle Dauchstein with a ministerial family, which from then on called themselves von Bynheim and appeared in documents in 1343/44 with Heinrich von Bynheim.
In 1359, Johann von Binheim and his wife Ysengret von Helmstatt sold some small meadows and fields in Zuzenhausen to Gerung von Helmstatt. After the lords of Binheim apparently died out in the male line at the end of the 14th century, the castle passed to the lords of Helmstatt (Asbacher Ast). 1398-1421 Ysengret's brother, Swicker the Elder von Helmstatt, appears as lord of the castle. 1423-1426 then his son Swicker the Younger and 1423-1448 his brother Hans. The construction of the Palas, only the remains of which can be seen today, also took place during this period. Hans von Helmstatt and his wife Margarete von Angelach finally sold Dauchstein Castle and the town of Binau to Dieter von Bödigheim in 1448.Source: de.wikipedia.org/wiki/Burg_Dauchstein
