Østermarie Church was originally built in the early 13th century. While it was being demolished in 1890, it was discovered it was of considerable architectural interest and work was stopped. The new church from 1891 is also in the Romanesque style.
The new church was built on the place where the old church tower once stood. The architect was Andreas Clemmensen who was involved in the design of Christiansborg Palace. Built in the Romanesque style, it consists of a tower, nave, chancel and apse together with two cross pieces. The outer wall is granite from the nearby Paradis quarry.
The rear wall of the altar is topped by seven candles in a seven-armed candlestick. The limestone font (ca. 1250), in late Romanesque style, comes from Gotland. The pulpit has four carved panels in oak from 1593. In the northern cross arm, there is an epitaph to Jens Kofoed, popularly credited with the liberation of Bornholm from the Swedes in 1658. The cross below the chancel arch, added during the church's restoration by the architect Rolf Graae in 1964, is the work of Paul Høm, a local artist.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.
