It is open to the public.HistoryOne of only eight surviving pre-1800 buildings in Manhattan, the hotel was originally built as a carriage house and stable in 1799 for a nearby estate. Owner Joseph Coleman Hart converted it into a hotel in 1826. The Mount Vernon Hotel operated in a city experiencing huge commercial growth after the opening of the Erie Canal. Its location offered guests a respite from the dirt, noise, and bustle of city life. In the 1830s, the commercial shipping and business districts of New York City lay below City Hall, while private residences extended as far north as modern-day Chelsea, and it was common for upper- and middle-class residents and visitors to take day trips to the then-rural setting that is now midtown Manhattan. One of over 50 day hotels in or near New York City, the Mount Vernon attracted middle-class guests with leisure activities like boating trips, unusual exhibitions, reading, and making new friends. In a city without public parks or public libraries, these day hotels offered “gentlemen and their families” and other guests new ways to have fun. They could escape the explosive growth of New York City's population and the ensuing urbanization (the population of New York City, 123,706 in 1820, had grown to 202,589 by 1830) and spend a quiet day near the river and be home downtown by sunset.
