Erfurt is a popular tourist destination with Germans and, increasingly, with English-speaking visitors for two reasons: It has one of the most attractive medieval city centers in Germany, with patrician townhouses, half-timbered buildings, Europe's longest inhabited bridge, and enough churches to be called "The Rome of Thuringia." It's an important stop on the "Luther Trail" from Eisenach to Wittenberg, with Lutheran landmarks such as the Augustinian Monastery and the Michaeliskirche. (Luther received his university education, became a monk, and entered the priesthood in Erfurt.)
