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!

    "The retaining wall on Itin is built from stones from the old Western Pennsylvania Penitentiary, which was torn down in 1886. The retaining wall on Troy Hill Road is built from stones from the old Western Pennsylvania Penitentiary as well. The original Western Penitentiary was completed in 1825 and was built in the Allegheny Commons area. A plaque marking the site is in the eagle enclosure at the National Aviary. In 1882, a new prison was built along the Ohio River, where it remains."
