The neoclassical church of Askainen was built by the owner of Louhisaari Manor, Governor-general Herman Claes'son Fleming in 1653 as the chapel church of Louhisaari Manor. It’s one of the rare stone churches in Finland built after the Reformation in the 17th century. The belfry was erected in 1772–1779. There is a funeral chapel of the Mannerheim family in the cemetery.
The Askainen noblemen's church is part of the oldest tourist route in Finland, the Seven Churches Tour, together with Raisio, Masku, Nousiainen, Lemu, Merimasku and Naantali. Finnish National Board of Antiquities has named the church and near Louhisaari manor 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.
