The Forum Marinum Maritime Centre exhibits seafaring history and traditions of the nautical culture in the southwest of Finland, history of the naval forces and the maritime history collections of Åbo Akademi University and Provincial Museum.
In addition to permanent and temporary exhibitions there are several museum ships located to the museum or near Aurajoki river. Most well-known ships are full-rigger Suomen Jousten (built in Saint-Nazaire in 1902) and barque Sigyn (built in Gothenburg in 1887). Finnish naval forces are also well represented including the minelayer Keihässalmi and the corvette Karjala.
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
