"Before and After of Halcyon Hall, Millbrook, NY.

The main building of Bennett College, Halcyon Hall, was built in 1893 by H. J. Davison Jr., a publisher from New York. The 200-room Queen Anne structure was designed by James E. Ware. It has five stories, a basement and sub-basement. Originally built as a luxury hotel, the building became home to Bennett College in 1907 after the hotel failed to catch on. The Bennett campus also included a chapel, stables, dormitories, an outdoor theater, and the Kettering Science Center, a state of the art building completed in late 1972. The cost of constructing the science building (needed to comply with new state science education requirements), along with other campus upgrades, contributed to the school's bankruptcy.

Halcyon Hall was never reopened and quickly fell into ruin. As of early 2021 the building is still standing."
