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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
