Gudsberga, Cistercian monastery ruin in Husby parish, Hedemora Municipality, Sweden

Gudsberga is a partly excavated Cistercian abbey ruin in the village of Kloster, Hedemora Municipality. Its three-aisled stone church, with a polygonal choir, was excavated in 1959–1961 and measures 21 by 44 metres, larger than the mother church at Alvastra. No stone foundations of convent buildings have been found, so those were probably timber-built. The ruin is part of the Husbyringen eco-museum.

Gudsberga was founded in 1486 by the Dalarna district judge Ingel Jönsson Hjorthorn and his wife Birgitta Sonedotter as a daughter house of Alvastra Abbey. It was Sweden's last Cistercian monastery and Dalarna's only one, wealthy from estates, smelters and mine shares. From 1527 Gustav Vasa's reduction brought it to the crown; it was enfeoffed in 1538, and in 1544 the king ordered its silver sent to Stockholm.

The name Gudsberga means "Mons domini", the Lord's mountain. The abbey was founded in 1486 by the knight Ingel Jönsson Hjorthorn, häradshövding of Dalarna, and his wife Birgitta Sonedotter, as a daughter house of Alvastra. The ruins lie in the village of Kloster and form part of the Husbyringen eco-museum; on 14 September 2025 Bishop Mikael Mogren led a pilgrimage mass at which the altar was used again, with some 200 participants.

The site is accessible via marked walking paths with informational panels explaining the layout of the former monastic buildings. It remains open to visitors year-round and offers a straightforward walking experience in an open rural setting.

The church measured 21 by 44 metres, larger than the mother church at Alvastra, yet its plan departs from standard Cistercian layouts and is judged less carefully built than is usual for the order. No stone foundations of convent buildings have been found, suggesting the monks lived in timber structures.
