The St. Olaf's Church in Tyrvää is a late medieval stone church built probably in 1510-1516. Archeologists have found evidences that the church site has been a spiritual place even in 1000 BC. The settlement has concentrated to the Vanhankirkonnimemi area during the end of Iron Age. There may have been two wooden churches before the present one built in the 14th century. The St. Olaf's Church was probably extended in the 17th century by local family of Nuutila.
When the new wooden church was completed in 1855, St. Olaf's church was abandoded for one hundred years. The church was well known of it's unique interior, until it was burnt down by a pyromaniac in 1997. The church was rebuilt by local people and the interior paintings were created by painters Kuutti Lavonen and Osmo Rauhala.
Finnish National Board of Antiquities has named the church site as national built heritage.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
