Västerhus kapell, Church ruin in Östersund Municipality, Sweden

Västerhus kapell is a ruined stone church on the western tip of Frösön, built in the 12th century on the site of an earlier stave church from around 1050. Its rectangular nave had a western tower and a narrower straight chancel to the east, with an apse that was never fully completed. The walls were demolished in 1952 for the F4 airfield runway; today stone slabs in the ground mark the foundation, with a sunken memorial stone inscribed by Aksel Lindström.

The chapel was built in medieval times and later served as Jämtland's first school location from 1578 to 1597. Archaeological excavations in 1947 uncovered 364 medieval skeletons that provided insights into the local population of that era.

The chapel served as the first school location in Jämtland from 1578 to 1597, established by the bishop of Trondheim under King Frederik II's command.

The site is designated as an archaeological research area and protected as Riksantikvarieämbetet RAÄ No. 2528-K-0000-00-0010. Visitors should expect minimal signage at the ruins and check the relevant authority's website for current access information.

Of the 364 skeletons moved to Stockholm in 1952, 184 belonged to individuals who died before the age of seven, and 27 more were between seven and 14. The remains are still held at the State Historical Museum in Stockholm despite repeated appeals to return them to Frösön for reburial.
