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