Linienwall#
Linienwall, former outer fortification of Vienna, built in 1704 because of Kuruc invasions as earth embankment with trenches, lined with bricks in the 19th century. Surrounded Vienna where today the Guertel circular road runs in a semicircle from the Danube canal near St. Marx across the foot of the Wienerberg mountain to Lichtental. Gates with toll-houses (called "Linien"). At the turn of the 18th to the 19th century the drawbridges were removed and the trenches at the Linien toll-gates were filled. During the October revolution of 1848 the rebels barricaded the gates of the toll offices. Later the toll offices were only used for the collection of the consumption tax (from 1829). The Linienwall separated the suburbs (today districts 3-9) from the rural villages (10th -19th districts) and was razed after these areas became part of the city in 1893; it was replaced by the Guertel, an outer belt boulevard, with green areas and city railway (today U 6 subway).
