Explorer Colmar

The Unterlinden Museum occupies a 13th-century Dominican convent and opened to the public in 1853. Around its Gothic cloister it shows Upper Rhine art of the 15th and 16th centuries, including Matthias Grünewald's Isenheim Altarpiece in the former convent church, while a 2015 extension by Herzog & de Meuron holds the modern collection.

St Martin's Church is a Gothic collegiate church built of Vosges sandstone between 1234 and about 1365 on the site of earlier churches. Often called the cathedral, it held that role only briefly after the Revolution. It has a coloured tiled roof, a 71 m tower with a lantern added after a fire in 1572, an ambulatory and a Baroque organ case of 1755.

The Toy Museum of Colmar opened in 1993 in a former neighbourhood cinema on Rue Vauban and has been run by the city since 2024. More than 1,000 toys from the 19th century to today fill three floors, from old teddy bears and dolls to Barbie, Playmobil, robots and video games, and a model railway runs across the whole second floor.
