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.)
The U.S. Steel Tower, also known as the Steel Building, or USX Tower (1988–2001), is a 64-story skyscraper at 600 Grant Street in downtown Pittsburgh, Pennsylvania. The interior has 2,300,000 sq ft (210,000 m2) of leasable space. At 841 feet (256.3 m) tall, it is the tallest building in Pittsburgh. It held its opening dedication on September 30, 1971.

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.
One of the best examples of Art Deco in Pittsburgh, this building is constructed with Indiana limestone and has a polished granite base, a dark copper roof, and marble walls in the lobby.
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.
A sleek 55-story building which holds the title of the city's second tallest building. It is situated directly across from the U.S. Steel Tower, separated by only a street and a small park, standing as if to challenge the older and larger lion that is the Steel Tower. One of its unique features is the building's eight-sided design.
