Ever wish you could step back in time and spend a day in old New York? Drink some bathtub gin at a speakeasy or ride the original, elevated train? Well, now you can–at least through pictures. The website WhatWasThere ties historical photos to Google Maps, allowing users to tour familiar streets and neighborhoods. People from all over the world can upload their old photos and tag them with the location and year taken. Pretty simple, huh? The site hopes that if “enough people upload enough photographs in enough places” it will weave together a photographic history of the world.
