3. Park Slope Armory
In the grand entrance of the Park Slope Armory, now part of the Park Slope Armory Women’s Shelter, there’s a vintage double phone booth. On the left side of the booth there’s a light (still working) that once illuminated the phone book. A visit to the Park Slope Armory, most go to use the facilities of the YMCA, warrants a stop at the hidden Veteran’s Museum inside as well.
