Located on the corner of Market and 17th Streets, One Liberty Place was Philadelphia’s first supertall skyscraper and is currently the third-tallest building in Philadelphia. Architect Helmut Jahn used New York City's Chrysler Building as a reference when designing One Liberty Place. One Liberty Observation Deck opened on the 57th floor in 2015, becoming the highest publicly accessible floor in Philadelphia at the time.
Visitors to One Liberty Observation Deck get a breathtaking look at the historic Philadelphia skyline from a one-of-a-kind vantage point.
