Halcyon Hall, Bennett College, Millbrook, New York

Halcyon Hall was originally built as a luxury hotel in 1890, but closed in 1901. However, the hall enjoyed a second life when, a few years later, the Bennett School for Girls moved in, making the building home and school to students from prominent families. However, with the rise of coeducational schooling, the Bennett failed to thrive, going bankrupt and shuttering its doors in 1978.
