The Perniö Church was built in the 15th century, probably in 1460-1480. It's dedicated to St. Lawrence (as well as many medieval churches in Finland). The interior contains mural paintings made by the school of famous artist Petrus Henriksson from the end of 15th century. There are also seven limestone tombs inside the church. The belfry was erected in 1746.
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.
