Åre Old Church was built in the late 12th century entirely in stone, with inspiration from contemporary Norwegian church buildings, since Jämtland then was a part of Norway. It is situated at the Saint Olaf Pilgrim's Route (S:t Olofleden), and nowadays is the seventeenth stop on the route that goes from Selånger Old Church ruins at Sundsvall, situated at the Gulf of Bothnia, and crosses the Scandinavian Mountains via Stiklestad to the Nidaros Cathedral in Trondheim, Norway — and remains the only stone church in the Scandinavian Mountains from the Middle Ages. Other remaining medieval churches in the Scandinavian Mountains are stave churches situated in Norway.
The original church's interior dimensions were only a mere 5x11 metres, with a choir of 2.5x2.5 metres. There were only three tiny windows, so it was quite a dark church. Preserved medieval artifacts in the church are two ship candlesticks, a processional cross and an unusual wooden statue of Saint Olaf. The statue does not show him as usual with an orb in his left hand and a war axe in his right wearing a crown, but only with an orb in his left hand wearing a tricorne uniform hat of the Caroleans. The wooden statue itself was dated as being from the 14th century, but it can be older.
After centuries of warfare between Denmark–Norway and Sweden, the Second Treaty of Brömsebro made Jämtland a part of Sweden. In 1673 the church had a pulpit installed at the southern church wall according to Norwegian traditions. The baptismal font and gallery at the northern church wall also dates from the end of the 17th century. In 1736 the church was extended almost 12 metres to the west. The old choir was converted into a sacristy, and the new entrance of the church was placed to the west with a porch in stone.
A mighty reredos was added over the new altar depicting the mourning Marys and the crucifixion of Christ in the centre. Higher windows were added as well as the current pews. The characteristical bell tower was erected during the 1750s by Erik Olofsson i Rännberg. It belongs to a group of typical belltowers of the 18th century Jämtland with its onion-shaped cupola.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
