The Graben is one of the most famous squares in Vienna's first district, the city center. It begins at Stock-im-Eisen-Platz next to the Palais Equitable, and ends at the junction of Kohlmarkt and Tuchlauben. Another street in the first district is called Tiefer Graben (deep ditch). It is crossed by Wipplinger Straße by means of the Hohe Brücke, a bridge about 10 meters (33 ft) above street level.
