This little corner of the Diamond (the Diamond is called “Market Square” on maps) looks like the Pittsburgh of olden times, before steel-cage construction made skyscrapers sprout everywhere. Taking away the neon and the road signs, it could be a Victorian engraving. Father Pitt begs your forgiveness for the cheap lens on this digital camera, which makes straight lines impossible. (Update: With better software, we have been able to eliminate most of the distortion. For comparison, the original image is reproduced below.)
The Diamond is a block up Forbes Avenue from the Gateway Center subway station.
