Vienna 2024

The Karl-Marx-Hof is a significant landmark in Vienna, Austria, and a prime example of the “Red Vienna” era of social housing. It is a Gemeindebau which is the German term for a type of municipal housing complex, a concept pioneered in Vienna during the early 20th century. The Karl-Marx-Hof is one of the longest continuous residential buildings in the world, stretching over 1,100 meters (0.68 miles).
