The historic old town is still surrounded by parts of the town wall with moats. It originated mainly in the 12th and 13th centuries. Several times in the town's past, large-scale fires or wars destroyed many buildings. A great fire destroyed nearly half the town's old quarter in September 1874. This part was rebuilt in the Neoclassical style with ornate buildings and straight streets. This style also characterizes the main shopping street, Georgstraße. In other parts of the old town half-timbered houses from the 16th to 17th century and large mansions from the 18th to the 19th century still predominate. Since 1990, some modern new buildings were added. The center is dominated by the "Stadtkirche" (town church). In the western part, the townscape has formed around "Schloss Elisabethenburg".
