After World War II, the military grounds were used as a dumping ground for debris from allied bombing, which in 1955 was covered in dirt by landscape architect Wilhelm Alverdes to form a Schuttberg which is located within the park. The park was named after Fritz Schloß (1895-1954), who was the mayor of the former district of Berlin-Tiergarten (since 2001 district Mitte) from 1946-52, which encompassed Moabit. The park contains a memorial by Alfred Frenkel dedicated to the Trümmerfrauen, the women who helped clear rubble and rebuild the city after the war.
