Glambæk castle ruins
Sad remains of a castle that was destroyed in the Thirty Years War. Only the moat and some brick walls are left today.
U-Boot-Museum

Peter-Wiepert-Museum
Museum about local geology, crafts, cultural history, and seafaring.
Tropical aquarium with sharks, mangroves, corals and a big underwater tunnel you can walk through.

Watch the ferries come and go and maybe catch a glimpse of the tunnel construction site.
