The Musée des Jacobins — officially the Musée des Beaux-Arts de Morlaix — occupies a converted Dominican convent whose Gothic nave provides a spectacular setting for its collections. The building itself is the first attraction: a high-vaulted medieval interior with 19th- and 20th-century additions, housing permanent collections of Breton furniture, religious art, and fine arts, alongside temporary exhibitions that tend toward contemporary work.
The Breton collection is the strong suit — carved wooden furniture, traditional costumes, faïence pottery, and objects from the Léon and Trégor regions surrounding Morlaix. The fine arts section covers French painting from the 17th to 20th centuries, with a decent showing of 19th-century landscapes and a few surprises. The medieval stained glass fragments in the nave are worth finding.
The museum is centrally located and makes a good rainy-afternoon option. Combined with the Maison à Pondalez a few streets away, it rounds out a picture of Morlaix's history as a prosperous trading town.
