Octagon Hotel
New York, United States
The Octagon Hotel, built as the Nassau House by Luther Jackson in 1851 (1851), was a pre-eminent political and social meeting space in Oyster Bay, New York. This eight-sided building is also believed to be among only a few like it on Long Island and perhaps the only octagon-shaped hotel in the United States.
