An Art Deco edifice completed in 1932, this building was the city's tallest (and for that matter, the state's tallest) until the U.S. Steel Tower was completed in 1970. Today, it's the city's sixth tallest. The building is named for the Gulf Oil company, and the top of the tower is designed to resemble a step-pyramid/mausoleum which is illuminated at night with a coded system that shows the current weather with colors, or to celebrate the local teams' achievements and the holidays.
This lovely church looks particularly out of place next to the massive office buildings surrounding it, but serves as an interesting reminder that this was once a residential area.
Formerly known as the USX Tower
A 64-story triangular office building which is the tallest in Pittsburgh, and briefly held the honor of being the tallest building in the world outside of New York City and Chicago. It was built in 1971 of a special type of steel, "Corten" steel, developed by USS. It is not painted and is intended to rust to a tough, brown finish and then stop rusting. (One hopes.)
