St. Marx Cemetery (Sankt Marxer Friedhof) is a cemetery in the Landstraße district of Vienna, used from 1784 until 1874. It was named after a nearby almshouse. The cemetery was opened in response to a decree by Emperor Joseph II that forbade further burials in cemeteries within the outer walls of the city of Vienna. He also ordered that bodies should be buried unembalmed and without coffins in mass graves. (Wikipedia)
