Retrographer harnesses the knowledge of the community to create a collaborative map of Pittsburgh's historic photographs.

How it works?

All of the photographs on the site come from the City Photographer collection hosted and curated by the University of Pittsburgh's Archives Services Center

Retrographer uses Google Maps to make it easy for anybody to geotag these images. This geotag data is sent back to the Archives Services Center to become a permanent part of the archive.

About The Project

Retrographer was started in the Fall of 2010 as a project for the Senior studio Pieces taught by Dylan Vitone at Carnegie Mellon University. The project has evolved and lives on after the class has ended. So far over 3,900 photos have been tagged by people all over Pittsburgh

Retrographer continues to evolve. Check back soon on your smartphone, a mobile app is on the way.

Just Pittsburgh?

It doesn't have to be. If you would like to bring Retrographer to your city, and are able to work with an archive or museum to get access to a collection like Pittsburgh's City Photographer Collection, shoot me an email!

    "this was a fun one - so in the modern location the Allegheny County Morgue (now the Health department) is on the right. However in the picture from 1913, it is on the right. This is because in 1929 they moved the building to it's present location to allow the construction of the county office building."

    "I lived a couple blocks from this corner - Wylie at Chatham St. Chatham was just two blocks out from 6th Ave. Enlarge the photo and see the Chinese Laundry owned by the family of a good friend and classmate. They lived above it. So many households and businesses were forced to move in the late 50s. ------(The map you see on this page doesn't show the way things were. For example , Centre did not go into this part of the Hill. It didn't go below where Crawford is now.)"

    "This was a very lively section of Wylie and the Hill District back in the 40s. All cleared for the old Civic Arena in th 60s. Now just all cleared for parking lots. Prime real estate, development plans unknown."
