2. Middletown State Homeopathic Hospital, Middletown, New York

The Middletown State Homeopathic Hospital is located in Middletown, New York and was first opened in 1874. At the time of its opening, the facility was the country’s first purely homeopathic hospital for mental disorders, which meant that the facility was home to many new techniques that were deemed obscure. Patients were treated with arts activities, an institutional newsletter written by the patients themselves, strict dietary regiments, and most famously, baseball.

The hospital’s baseball team, the Middletown Asylums, began playing in 1889 and eventually began playing some of the region’s best teams, including the New York Giants. Some of the team’s players even went on to play in the majors.

The hospital was eventually closed in 2006 and was left abandoned.
