The Hufeisensiedlung is a housing estate in Berlin, built in 1925-33. It enjoys international renown as a milestone of modern urban housing. It was designed by architect Bruno Taut, municipal planning head and co-architect Martin Wagner, garden architect Leberecht Migge and Neukölln gardens director Ottokar Wagler. In 1986 the ensemble was placed under German heritage protection. On July 7, 2008, it was awarded UNESCO World Heritage status as one out of six Berlin Modernism Housing Estates. Since 2010, the Horseshoe Estate has also been listed as a garden monument. The Hufeisensiedlung is probably the most outstanding example of innovative German town planning during the 1920s.
