Engraving from 1770-1780 showing Augsburg's Ulrich Square ("Ulrichsplatz") with the fountain of Hans Felber (a hydraulic engineer from the 15th century). Ulrich Square is facing the Abbey Church of St. Ulrich and St. Afra (not visible). In the foreground, the pillar displaying the coat of arms of Augsburg, topped by the distinctive pine cone, probably serves as a boundary marker with, on one side, the Free Imperial City of Augsburg, and on the other, the Imperial Abbey of St. Ulrich and St. Afra. Both entities were fully independent of each other.
