The Old Church of Loppi, also known as Santa Pirjo (St. Birgit), was built in 1660s. The history of simple and bare wooden church is quite unknown because documents of building were destroyed by fire. According some investigations the church could be completed already in the tide of 15th and 16th centuries, but the age of wall logs is dated to the year 1666.
Only couple of tombs remain of the old cemetery near the church. Nowadays Loppi Old Church is popular wedding and concert church.
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.
