Dragsmark Abbey, Monastery ruins in Uddevalla Municipality, Sweden

Dragsmark Abbey comprises stone ruins located near a fjord, with remaining walls that reveal the layout of the former buildings. The visible foundations of the church, sacristy, and chapter house allow visitors to trace the original structure and daily organization of the site.

The monastery was established before 1260 with support from King Hakon Hakonsons and operated as a Premonstratensian community. It ceased functioning in 1519 when it became the first to undergo secularization in the region.

The abbey is linked to the ballad of Sir Axel Tordsson and fair Valborg Ingemarsdotter, a tragic love story set at Dragsmark and known in Bohuslän by the early 18th century. The Danish poet Oehlenschläger used it for his play Axel and Valborg, moving part of the action to Trondheim Cathedral. A medieval English chalice, said to be given by King Håkon Håkonsson, was used in the parish until the 1970s.

The ruins lie on the western tip of the Bokenäset peninsula, beside Dragsmarks kyrka, on the fjord between Uddevalla and the sea, north of Orust. The church plot was cleared around 1900 and its massive foundation walls exposed to a height of one metre, so the ground is uneven. The conventual buildings to the south are only partly excavated.

The stones from the deteriorating monastery buildings were repurposed in 1610 to build the nearby Bahus Fortress. This transformation shows how religious structures were converted into military defense works.
