Built in 1904 and designed by famed architect Rafael Guastavino. This station was intended to be a show piece of modern design, and as such includes many unique features such as hanging chandeliers, elaborate tile work, leaded glass skylights, and graceful arches.
The station proved less than popular over the years, and by 1945 it's short curving platform and low ridership caused it to be shuttered from public use.
The New York Transit Museum currently runs tours through the station… and this is how I visited it in June 2014.
