This narrow medieval street, walled in on one side by the bare cliffs of the Kapuzinerberg, was originally the ancient Roman entrance into the city from the south. The houses stood along the riverfront before the Salzach was regulated. Nowadays it's a fascinating mixture of shops and nightclubs, but with its tall houses the street still manages to convey an idea of how life used to be in the Middle Ages. The Steintor marks the entrance to the oldest section of the street; here on summer afternoons the light can be particularly striking. House No. 23 on the right still has deep, slanted peep-windows for guarding the gate. House No. 31 is the birthplace of Josef Mohr, the poet of "Silent Night, Holy Night" fame (not No. 9, as is incorrectly noted on the wall).
