Sydenham Hospital for Communicable Diseases, also known as Montebello State Hospital or Montebello State Chronic Disease Hospital, was a hospital and is a national historic district in Baltimore, Maryland, United States. It was originally constructed in 1922–1924, and the campus consists of seven Italian Renaissance Revival style buildings: the main hospital building, the administration building, the kitchen, the nurses’ home, the laundry with servants’ quarters above, the garage, and the powerhouse. A residence for the Director of Medical Research was added in 1939. The campus was designed by noted Baltimore architect Edward Hughes Glidden.
