The mediaeval greystone church is dedicated to St. Olav and was built in the 1450's. Long ago, Lemu was part of the great Nousiainen ancient parish, but parted to an independent administrative and ecclesiastical parish in the Middle Ages. When an episcopal church was erected in the old mother parish, a sanctuary consecrated to St. Olav was built also in Lemu.
First, a small wooden chapel was raised on Toijainen hill probably in the 13th century. An old crucifix and a baptismal font in the present church date back to those times. In the 14th century a small stone chapel was built and it now serves as the sacristy. In the 1430's an imposing mediaeval stone church was erected, partly by the wealth of the noblemen, partly by the toil of the peasants.
There are several curiosities in the church, such as - the only one of its kind in Finnish churches - the coat of arms of Mauno Särkilahti (Stjernkors), a painting of Martin Luther, an old Bible and a note of Marshal Mannerheim’s participation in confirmation. The years 1380, 1450 and 1959 are marked in the church banner. The altarpiece ”The Resurrection” by von Becker dates back to the year 1880.
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.
