The Cathedral of Saint Mary of the Assumption is the Catholic cathedral of the diocese of Chur in Switzerland. The episcopal palace of the bishop of Chur is beside the church. The cathedral claims the relics of St Lucius of Britain, said to have been martyred nearby in the late 2nd century. During the Swiss Reformation, the Catholic population of the city were confined to a ghetto enclosed around the bishop's court beside the cathedral.
The first building on the site probably dates from the first half of the 5th century. The second church was built by Bishop Tello at some time before his death in 773. The current building was built between 1154 and 1270. In 1272 it was dedicated to The Assumption of the Blessed Virgin Mary. The round arch window along the center axis is the largest medieval window in Graubünden. The late-Gothic high altar was completed in 1492 by Jakob Russ.
In 1811 a fire destroyed the towers and roof of the cathedral. In 1828-29 the roof was replaced and the towers were rebuilt from the ground up. The marble floor in the choir was added in 1852. In 1884-86 the west window was reglazed and a new organ was built by F. Goll of Lucerne. Between 1921 and 1926 the entire church was completely renovated. The interior was completely cleaned, some of the plaster was removed from the walls, the altars were restored and the crypt floor was excavated. About a decade later, in 1937-38, another organ was added by Franz Gattringer of Horn in the Canton of Thurgau. For the rest of the 20th century a museum was added in the crypt and additional repairs, cleaning and renovations continued. For about six years, beginning in 2001, the cathedral was completely renovated and new organs replaced the Goll and Gattringer organs.
The west facade of the cathedral consists of a Romanesque portal with the large west window above. The portal is flanked by two simple pilasters. The iron work above the portal was created around 1730. The single bell tower is on the north side of the building between the nave and choir. It was completely rebuilt by Johann Georg Landthaler after the 1811 fire. The two story sacristy makes up the east end of the building. A 14th century round window is visible on the north side of the choir, along with three windows on the south side which were restored in 1924-25.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
