Kalix Church is the northernmost medieval church in Sweden. It dates from the 15th century (first mentioned in 1472). Several items of medieval inventory are preserved including the font, altarpiece and two sculptures. The pulpit, a Baroque work, is from 1674, and is among the oldest to be found in the north of Sweden. The church has a separate wooden belfry, which was made in 1731. The church has been sacked by Russian troops twice, in the 18th and 19th centuries; the adjacent church cottages were burnt down.
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.
