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:
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne"s court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
