The St. Mary's Church is a medieval stone church located in Maaria. There are no records as to when the present church was built, but the work was probably started in the mid or late 15th century. According to Markus Hiekkanen, the church was probably built in the 1440s. On the basis of the style of the closets, the gables were constructed about 50 years later.
There are medieval limestone paintings on the walls, which are not common to other places in Finland. The most valuable artefacts are the wooden alter cabinet and large altarpiece depicting Christ on the cross.
References: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.
