The Insane Asylum was completed in 1855 and operated until 1935.
Before then, patients with mental illnesses were often kept chained
in jails and attics of homes.
According to records, of the 1,376 patients admitted between 1855 and
1877, more than one in five died.
After the US Civil War the facility expanded dramatically, eventually
housing about 6,000 patients during its peak.
The first coffins were discovered by the university in 2013 while
constructing a road near campus.
In 2014 officials found more than 1,000 coffins while building a
parking garage.
