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 Goseck circle is a Neolithic circle structure. It may be the oldest and best known of the Circular Enclosures associated with the Central European Neolithic. It also may be one of the oldest Solar observatories in the world. It consists of a set of concentric ditches 75 metres across and two palisade rings containing gates in places aligned with sunrise and sunset on the solstice days.
Its construction is dated to c. 4900 BC, and it seems to have remained in use until 4600 BC. This corresponds to the transitional phase between the Neolithic Linear Pottery and Stroke-ornamented ware cultures. It is one of a larger group of so-called Circular Enclosures in the Elbe and Danube region, most of which show similar alignments.
Excavators also found the remains of what may have been ritual fires, animal and human bones, and a headless skeleton near the southeastern gate, that could be interpreted as traces of human sacrifice or specific burial ritual. There is no sign of fire or of other destruction, so why the site was abandoned is unknown. Later villagers built a defensive moat following the ditches of the old enclosure.
The Goseck ring is one of the best preserved and extensively investigated of the many similar structures built at around the same time. Traces of the original configuration reveal that the Goseck ring consisted of four concentric circles, a mound, a ditch, and two wooden palisades. The palisades had three sets of gates facing southeast, southwest, and north. At the winter solstice, observers at the center would have seen the sun rise and set through the southeast and southwest gates.
Archaeologists generally agree that Goseck circle was used for observation of the course of the Sun in the course of the solar year. Together with calendar calculations, it allowed coordinating an easily judged lunar calendar with the more demanding measurements of a solar calendar.
