Two colliding grids make up downtown Pittsburgh’s street layout, and the collision happens at Liberty Avenue, giving us a fine array of odd-shaped buildings. This triangular structure, built as a bank, now houses the Wood Street subway station below and the Wood Street Galleries, an important contemporary art gallery, on the upper floors.

While the Gateway Center Station is closed, Wood Street is the terminus of the subway downtown.

This picture was taken with a Kiev-4 camera, a Ukrainian rangefinder that Father Pitt loves with an unreasoning passion. He would like to state for the record that the hideously rusted car in the foreground is not his fault.
