Aabenraa used to be the main town in Sønderjylland and was known for its maritime industries. The town was built around 1200 AD. Many of the buildings have a historical tale to tell, especially Brundlund castle, which Queen Margrethe I built in the 1400s. Have a wander through the town, enjoying the ambient old quarter with street names that tell their own stories, such as Slotsgade (Castle road) and Store Pottergade (Large Potter Street). Follow the promenade from the harbour and arrive at Sønderstrand, where you won’t be able to resist a quick dip!
