The castle Schloss Johannisburg in Aschaffenburg was erected between 1605 and 1614 by Georg Ridinger. Until 1803 it was the second residency of the prince bishop of Mainz. It is made of red sandstone, the typical building material of the area around Aschaffenburg.
The castle is one of the main attractions of Aschaffenburg and its landmark. It is located in the center of the city, overlooking the waterside of the river Main. An old keep from the destroyed 14th century castle was included in the construction which is now the oldest part of the castle. Schloss Johannisburg is one of the most important buildings of the Renaissance period in Germany. At the end of the 18th century the interior was restructured in neo-classical style.
