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.
Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
