Time travel may not be possible, but with just an internet connection, you can now take a virtual tour of old New York, thanks to a new mapping tool.

Old NYC is a project from software developer Dan Vanderkam, who used archival photographs from the New York Public Library to build a rather outdated — though very interesting — map of the city. Like Google Street View, you can click on various dots on the map and see a photograph of what that street used to look like. The photos display details about the address, the date of the photo (if it’s available) and any comments people have posted (the site is interactive).

According to the site, many of the photographs are the work of Percy Loomis Sperr, a photographer who documented the city from the late 1920’s to the early 1940’s.
