Halcyon Hall, Bennett College, Millbrook, New York
The Halcyon Hall started out as a luxury hotel when it was built in 1890. It had five stories and over 200 rooms but it did not do as the owner had planned. The hotel closed down in 1901. In 1907, a school teacher decided to move her school for girls into the building. Eventually, more buildings were added to the estate and it became a fully-functional college known as Bennet college. However, with more coed colleges coming up in the country, the college fell into debt and was finally abandoned in 1970s. The building was demolished in 2014.
