Construction on this Gothic cathedral began in the 14th century, but the current version was only fully completed in 1890. The interior of the Münster contains gorgeous choir stalls by Jörg Syrlin (1469–1474) from the 15th century. The top of the steeple, which is the tallest in the world, can be reached by climbing 768 steps and offers an amazing view of Ulm and the region (7€ for adults). On clear days, it is possible to see the Alps.
