Rothenberg Fortress (German: Festung Rothenberg) is a fortress on the eponymous hill, 588 m, near Schnaittach in the Franconian Jura.
The first fortifications were probably built between 1300 and 1330 by Dietrich von Wildenstein. He sold it in 1360 to the emperor and Bohemian king, Charles IV, who had the fort upgraded into a border castle in order to protect his Bohemian allodial estate.
In 1478, Count Palatine Otto II set the condition for Rothenberg Castle to become a joint-fief or Ganerbenburg. 44 co-vassals who, together with the town of Rothenberg and market town of Schnaittach, acquired the castle as a so-called mesne fief or Afterlehen, were given relatively little property and few rights, but the community of co-vassals formed a strong alliance to which other members of noble families in the area could be attached. The castle also had several rights of patronage in the Nuremberg area. The community of co-vassals had the characteristics of a type of union called an Einung. At the time of Silvester von Schaumberg the castle was a "wasp's nest" - which even princes feared to fall out with.
The community of co-heirs nominated a burgrave.
In the 18th century an important Rococo fortress, based on a French prototype, was built on the site by the Elector of Bavaria and German Emperor, Charles VII. Construction lasted from about 1729 to 1750. Two bastions were named after him and his wife, Maria Amalia. From time to time up to 400 soldiers were garrisoned here. It was built on an older and smaller fortification that was slighted, which in turn had been built on the remains of an even older ruined castle.
