The first stone church in Orsa was built during the 13th century and maybe it replaced an old stave church. Around 1300 the church was built out in east direction and then maybe the sacristy came. In the middle of the 14th century the church was beamed out to the present beam. In the end of the 15th century it was built out to the present size, except the choir.
In 1607 they planned to build the bell tower at the western part of the church, and it was finished in 1639, but demolished and replaced by a new tower which was built in 1853, according to drawings by architect Ludvig Hawerman. The present choirs came when the church was rebuilt 1752–55. In 1979 the church was restored; the roof was rebuilt and a little museum was built in one of the tower rooms. The fore part of the floor was replaced by new limestone floor and the rest of the floor is made of sandstone from Orsa. At the restoration they found remains of two old floors made of stone and brick.
The triumph crucifix was made in Northern Germany in the late 1300s. The baptismal font dates from 1531.
References: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.
