Built in about 1872, the Waterfront Building is one of the unique row of surviving riverside commercial buildings Pittsburghers call Firstside. It dates from the time when the Monongahela wharf was a chaotically busy place, with steamboats lined up at every available space to load and unload. Now it is separated from the river by a boulevard and an expressway. Above, the First Avenue side; below, the river side.
