Aschaffenburg is a large town in northwest Bavaria, Germany. It is located on the right bank of the Main at the foot of the Spessart. It is also known as the Tor zum Spessart or "gate to the Spessart." Although it is within Bavaria, the town inhabitants claim to be Franconians, not Bavarians. Its chief buildings are the Schloss Johannisburg, built (1605-1614) by Archbishop Schweikard von Kronberg, which contains a library with a number of incunabula, a collection of engravings and paintings; the Stiftskirche basilica, founded in 974 by Otto of Swabia, duke of Bavaria, but dating in the main from the early 12th century on, in which are preserved various monuments by the Vischers, a sarcophagus with the relics of Saint Margaret, and a famous painting by Matthias Grünewald; the Capuchin hospital; a theatre, which was formerly a house of the Teutonic Order; and several mansions of the nobility
