Gürtel#
Guertel, Vienna, broad, tree-lined avenue that generally follows the course of the former Linienwall; it starts in the north-western part of the 9th district, runs in a concentric line around the old districts, with the exception of Leopoldstadt (2nd district) and is 1.5-2 km away from the Ringstrasse boulevard; it clearly separates the "inner" (districts 3 - 9) and the "outer" districts (10 -19). The western section is divided lengthwise by the tracks and stops of the former Stadtbahn transit line ("Guertellinie", now U 6 underground and elevated line), the eastern end (between 3rd and 11th districts) has not been developed commercially.
