The Museo Diocesano Regina Coeli occupies a former Clarissine convent on the edge of the historic centre. Its collection spans religious art from the Cantabrian region across several centuries: painted panels, gilded altarpieces, Baroque sculpture, liturgical objects, and votive images. The convent building itself is attractive, with a 17th-century cloister that provides a quiet counterpoint to the bustle of the main tourist streets.
The museum is particularly strong on Baroque religious sculpture, with works from local workshops that show the quality of craftsmanship that once existed throughout this part of Spain. There is also a collection of medieval stone carving and architectural fragments from churches in the surrounding region that were demolished or fell into ruin. Not the most obvious attraction in town, but worthwhile for anyone interested in Spanish religious art.
