This amazing website has been out for some time, and I keep forgetting to post about it.
Complete with a slider, the interactive map literally allows you to take a stroll through time and see how much Pittsburgh has changed…or didn’t.
The best part is, the site looks to the collective knowledge to help identify old photos and locate them over a google map, so you can compare the modern street view to the old image.
Over 5,000 images have been mapped so far, with plenty more that need your help locating the site.
Say goodbye to your evening exploring this gem.
