The only building left from the original Fort Pitt, and the only pre-Revolutionary structure left in downtown Pittsburgh, is this modest little blockhouse, which somehow survived a century and a half of being surrounded by warehouses before Point State Park grew around it. These photographs were taken with an Ansco Speedex folding camera.

Two views from the northern end of the Sixth Street Bridge, now officially the Roberto Clemente Bridge. This is one of the famous Three Sisters; Pittsburgh is the only place in the world, it seems, where you can find three identical suspension bridges side by side. The pictures were taken to test a fifty-year-old Argus C4, which apparently passed the test.
