Columbusplatz A square in Vienna's 10th district, just outside the old 'tax border' (the present Gürtel parkway) and near the old Southern Train Station. In the 1890s it was a market square and these building were constructed. Today there is a shopping center behind me, the entire street in a pedestrian zone, and it leads directly to the new central train station.
DC Towers 1 Austria's tallest building - 60 floors, 220 meters high, recently completed on the "Danube City" area of Vienna, on the Danube's left bank. The second tower is already under construction although this one is far from fully occupied.
Vienna's Water By the ;middle of the 19th century Vienna had many epidemics of typhoid and cholera from polluted water. A 95 km long pipeline was built to fetch fresh mountain water from the Rax and Schneeberg mountains south of Vienna. The system, which runs by gravity, was finished in 1873, and now carries some 220,000 cubic meters of water daily - about half of Vienna's water. The pipeline is carried in aqueducts over valleys and in tunnels through the hills. There are three aqueducts inside Vienna itself. This one is in the 23rd district. They were totally renovated 2007-2011.
