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!

    "Never saw a map old enough of that street it seems, I was recalling a late 1960s one for the construction of the USX construction where there was but a small slither of it left. I stand corrected."

    "Tunnel was much more than an alley. It had a lot of traffic from 5th, thru Wylie, to Webster near where cars could get on Bigelow outbound. It's true that Tunnel ended 'near' where the USS bldg is now. Look at this old map - https://historicpittsburgh.... - From 5th Ave, going north, parallel streets were 6th Ave, Tunnel, Chatham, Fernando, Washington, and so on. I lived nearby as a kid.

    "Tunnel Street was an alley where the USX courtyard now stands. The tall building in the background is the still standing Oliver Building on Smithfield Street."

    "The Dravo Building in this picture was at 300 Penn Ave which is round about the place of Gateway Center. The now gone Barbeau Street was two blocks toward the point from Stanwix St."

    "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."
