Musée d’Unterlinden Colmar

Gathered around a Gothic-style Dominican cloister, this revamped museum hides a prized medieval stone statue collection, late-15th-century prints by Martin Schongauer plus an ensemble of Upper Rhine Primitives. Its stellar modern-art collection contains works by Monet, Picasso and Renoir. The star attraction, however, is the late-Gothic Rétable d’Issenheim (Issenheim Altarpiece), by painter Mathias Grünewald and sculptor Nicolas de Haguenau. Hailed as one of the most profound works of faith ever created, the altarpiece realistically depicts New Testament scenes.
