The highest church tower in the world is located in Ulm (see also Guinness Book of Records). From the “Ulmer Münster” (yes, you can climb up many stairs …!) you have a great view across the two cities. With a bit of luck and at the right weather conditions, you can even see the Alps! The Old Town of Ulm is especially charming and offers many medieval buildings, half-timbered houses and narrow alleyways to stroll around.
