The Sonnenstein Castle is a castle in Pirna, near Dresden, Germany. It housed a mental hospital, which operated from 1811 to the end of World War II in 1945. During the War, it functioned as an extermination centre for the Nazi Aktion T4 program. It was shut down following the war, and reopened in 1970.
