Hidden history
Found, Not Built
Once said to be the largest building in the United States by floor area, until the Pentagon. What the photos show is a stone Kirkbride front stretching out of sight.
Huge, then gone
The main Kirkbride building was demolished in 2015 after long debate.
Overcrowded
Records describe thousands of patients by the 1910s. Researchers ask who they were.
Samuel Sloan
Credited to Samuel Sloan, who is linked to dozens of asylums.
Questions worth asking
- Who filled these buildings so quickly?
- Why demolish rather than reuse?
Possible original uses
- A palace or institution of another kind
- A hospital in a broader sense
