What was formerly a moat along the old Roman encampment of Vindobona and later bordered the medieval city walls, has over centuries turned into a tout-chic shopping mall. So when tourists and shoppers promenade along one of the most famous streets in Vienna’s first district, they somehow trample on a previous trench („Graben“ in German) that was filled and levelled at the end of the 12th century. Once used as a marketplace Graben was more and more uplifted by construction-work to a chic-address in the Baroque Era. Next to Baroque- and Biedermeier house-facades various representative buildings at Graben – such as Ankerhaus and Grabenhof a.o. by Otto Wagner or Generalihof a.o. by Adolf Loos – date back to the Art Nouveau-period. A historically most notable sculpture on this boulevard is Pestsäule, a golden High Baroque-style column that was erected by Emperor Leopold I. It refers to the Great Plague of Vienna that occured in 1679. In fact most tourists do not come for a special sight to this grand pedestrian street, but more for the overall impression. No wonder as Graben is at the very center of illustrious Vienna leading from the no. 1 sight Stephansdom on Stephansplatz to the junction of Kohlmarkt and Tuchlauben.
