This curved connector hallway joined the two sandstone wards at the H. H. Richardson-designed Buffalo State Hospital, probably the most architecturally rich asylum in America. The curvature was a brilliant forethought - decades after the asylum was built, it was overcrowded, but it was impossible to fill this hallway, which acted as a fire barrier, with patient beds.
This is the grand receiving lobby of the abandoned Unit 2 building at Mont Alto Sanatorium in Pennsylvania. Unit 2 was a children’s preventorium; basically a prophylactic tuberculosis shelter for kids. This is the room at which parents would drop off their children, not knowing how long it would be before they would see them again (if ever). While most of the surrounding buildings are still very much in use as a geriatric center, Unit 2 was abandoned, and now decay has set in in this lobby - at the center of which, inset into the ground, is the Great Seal of the Commonwealth of Pennsylvania.
