Karl-Marx-Hof
Austria
Stand on Heiligenstädter Straße and try to see both ends at once. You cannot. The Karl-Marx-Hof runs for roughly a kilometre (the usual figure given is about 1,050 metres), and it is described as the longest continuous residential building in the world. Opened in 1930 in Döbling, Vienna's 19th district, and named after Karl Marx, it is treated as the icon of 'Red Vienna'. It is listed, and the city has also designated it a protected building zone, so what you are looking at is meant to stay exactly as it is.
