The first wooden church of Kristiinankaupunki was built between 1654 and 1658 on the site where the Ulrika Eleonora Church now stands, however it burned down on 16th June 1697. The building of the Ulrika Eleonora Church, which replaced it, was completed in 1700. The church was renovated and returned to use in 1965. The wooden church is a typical seaside church complete with a votive ship hanging from the ceiling. The ship building skills are also otherwise evident in the architecture of the church, for example in the ceiling structure. Outside the church is an old graveyard where the significant families of the city are buried. This churchyard also holds the graves of warriors of Kristiinankaupunki. Only a few services are held in the church each year. Ulrika Eleonora is a popular venue for summer weddings.
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.
