Halcyon Hall at Bennett College in Millbrook, New York
Halcyon Hall was built on the grounds of Bennett College in Millbrook, New York. It was originally intended to be a luxurious five-story hotel complete with 200 rooms back in 1890. Unfortunately, the hotel shut down in 1901.
Then in 1907, a New York school teacher relocated her school for girls to the former hotel and had other buildings built as well. This area eventually became a junior college known as Bennett College. But by 1977, financial struggles forced the college to go bankrupt and was abandoned until its demolishment in 2014.
