The well-restored old town, overlooked by the cathedral, stands high up among winding cobbled streets lined with old houses. One of the oldest buildings (late 16C), at no 20 Slotsgade, houses a ceramic collection: Ehlers Lertøjssamling. The Slesvigske Vognsamling in Simmerstedvej has a collection of horse-drawn carriages from the 17C, 18C and 19C. Finds from local archaeological digs are exhibited at the Archaeology Museum in Dalgade. Opposite, a group of 17C buildings makes up an open-air museum.
