1650 Market St.
One Liberty Place is currently the second tallest building and skyscraper in Philadelphia and the 21st tallest building in the United States. Completed in 1987, One Liberty Place has 61 rentable floors and is 945 ft (288 m) high, only two feet (0.6 m) shorter than the Key Tower in Cleveland, Ohio. One Liberty Place's spire echoes that of the Chrysler Building in New York City.
After One Liberty Place's completion, a slightly smaller sister building, known as Two Liberty Place, was built in 1990 within the same complex as One Liberty Place.
