If you’ve ever been to the South Side, you’ve surely noticed the giant clock face overlooking the flats.
At a whopping 60 by 60 feet, the Duquesne Brewery Clock was the largest single-face clock in the world when it was installed in 1933 and has been used for several brand advertisements over the years, including Coca-Cola and AT&T.
Originally located on a Mount Washington hillside, the clock was moved to the South Side in 1961 after being purchased by the Duquesne Brewing Company and has stayed there since. As of 2017, the clock face is free of any brand advertisements.
