About 70 miles northwest of New York City, Middletown is home to a curious relic of the state hospital system.  After the state hospital proper closed, some of the buildings were put to other use, and some were abandoned. Almost all of the main building was demolished about the early 1980s. Only a very small portion, at its southern end, was left standing; I've yet to get a clear answer why it survived. Even in comparison with historic images, this remnant is barely recognizable as part of the larger historic hospital building. It's upper story, dormers, turrets, and porches have all been removed, a treatment given to other existing buildings as well.

These pages show the exterior and interior images of the remnant of the main building, plus exteriors of other buildings. The last page of this set includes color and black-and-white infrared images.

UPDATE JULY 25, 2015:
The last remaining section of the main building at Middletown State Homeopathic Hospital burned on July 12, 2015. The structure was entirely demolished by the end of July 14. The hospital closed in 2006, and the main building was privately-owned when it burned.
