Old Castle Pappenheim

The Old Castle is the former residence of the Marshals of Pappenheim, and stands within the old town of the Middle Franconian city of Pappenheim at Graf-Carl-Straße 13.
The previous noble seat, today's Pappenheim Castle ruins, was no longer considered sufficiently good, which is why in 1593 Wolf Christoph zu Pappenheim added the Old Castle to an older building. The master builder was Franz Joseph Roth. The building remained the residence of the Marshals of Pappenheim until the construction of the New Castle.
