Augsburg's cathedral, which was built in the 9th century, stands out because of its square Gothic towers, the product of a 14th-century update. A 10th-century Romanesque crypt also remains from the cathedral's early years. The 11th-century windows on the south side of the nave, depicting the prophets Jonah, Daniel, Hosea, Moses, and David, form the oldest cycle of stained glass in central Europe. Five important paintings by Hans Holbein the Elder adorn the altar.
A short walk from the cathedral will take you to the quiet courtyards and small raised garden of the former episcopal residence, a series of 18th-century baroque and rococo buildings that now serve as the Swabian regional government offices.
