Mauthausen Concentration Camp Memorial

Mauthausen was declared a national memorial site in 1949. Bruno Kreisky, the Chancellor of Austria, officially opened the Mauthausen Museum on 3 May 1975, 30 years after the camp's liberation. A visitor centre was inaugurated in 2003, designed by the architects Herwig Mayer, Christoph Schwarz, and Karl Peyrer-Heimstätt, covering an area of 2,845 square metres (30,620 sq ft).

The Mauthausen site remains largely intact, but much of what constituted the subcamps of Gusen I, II and III is now covered by residential areas built after the war. In 2016, a number of prominent Poles including Shevah Weiss and the Chief Rabbi of Poland Michael Schudrich, sent a letter of protest to Ministry of Internal Affairs of Austria.
