 It is Europe's fifth largest hospital, both by number of employees and bed capacity.The origins of Vienna General Hospital go back to Dr. Johann Franckh, who donated properties in 1686, after the end of the second Siege of Vienna, at the corridor Schaffernack for the establishment of a military hospital.However, since money was lacking for the establishment of the buildings, the disabled veterans were quartered, including families, in the Kontumazhof (epidemic hospital), already in existence.
