Ulm

Ulm isn't considered part of the Romantic Road, but it's definitely worth visiting, if only for one reason: its mighty Münster, which has the world's tallest church tower (536 feet). Ulm grew as a medieval trading city thanks to its location on the Danube River. Today the proximity of the Old Town to the river adds to Ulm's charm. In the Fishermen's and Tanners' quarters the cobblestone alleys and stone-and-wood bridges over the Blau (a small Danube tributary) are especially picturesque.
