The Church of Rusko was built probably in 1510-1530 and was dedicated to St. Mary Magdalene. It's one of the smallest medieval churches in Finland. The wooden belfry was erected in 1744. There are three medieval crucifixes in church, other 11 are moved to the National Museum or to the Historical Museum of Turku.
The National Board of Antiques has named the church area, surrounding graveyard and near stone bridge 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.
