The old imperial city of Ulm, on the left bank of the River Danube and founded in AD 850, is the economic and cultural center of Upper Württemberg and the starting point of the Upper Swabian Baroque Highway. Even without its other interesting things to do, Ulm would be worth visiting for the magnificent Ulm Münster, topped by the tallest church spire in the world — it stands at an impressive 162 meters in height.Tourists interested in architectural attractions will appreciate Ulm's striking blend of old and cutting-edge modern architecture, often side by side. The city is also known for its many theater, opera, and dance performances; a first-rate professional orchestra; the large Christmas Market; and lively traditional festivals, such as Oath Monday and the Fishermen's Jousting Tournament.
