Over the course of the past two years, the decorative illumination at the crown of One Liberty Place at 1650 Market Street in Center City has been under renovation, as it is being upgraded with powerful lights that can be animated into various schemes and colors. Designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates (later known as the Liberty Property Trust), the tower was completed in 1987 and stands 945 feet and 61 stories tall. The contractor for the illumination upgrade is The Lighting Practice, which has also decorated the W/Element Hotel. The new lighting system is integrated with the My Liberty Lights program, which allows certain users to change the exterior lights atop the building once per day for a duration of five minutes.

A Look at Early Iterations of Liberty Place When It Was Planned to Rise Under 500 Feet in Height

7:30 am on August 23, 2021 By Thomas Koloski

The Liberty Place complex in Center City is known for being the first building in Philadelphia to dramatically break the unofficial 548-foot height limit that was set by the statue of William Penn on top of City Hall. Upon completion, One and Two Liberty Place were the tallest skyscrapers on the skyline, standing at a height of 945 and 848 feet, respectively. The towers were designed by Helmut Jahn and developed by Rouse and Associates, which eventually became Liberty Property Trust. In this feature, Philadelphia YIMBY takes a look back at a number of early iterations of the complex when the towers were planned to stand around or under 500 feet in height.

Over the course of the past few months, an upgrade of the decorative lighting system has been in progress at One Liberty Place at 1650 Market Street in Center City, where the light strips that highlight the angled top of the tower are being reworked. Designed by Helmut Jahn of Murphy/Jahn and developed by Rouse and Associates, the two massive skyscrapers of Liberty Place were the first in the Philadelphia skyline to boldly break past the informal 548-foot height limit established by the tower of City Hall nearly a century earlier.

Looking at Two Liberty Place, Philadelphia’s Fourth-Tallest Building, in Center City

8:00 am on June 8, 2021 By Thomas Koloski

The majority of the skyscrapers that dominate the Philadelphia skyline are the trophy towers that were built in the late 1980s. One of these buildings is the 848-foot-tall, 58-story Two Liberty Place at 50 South 16th Street in Center City, the city’s fourth-tallest building. The skyscraper is a part of the Liberty Place complex that consists of two towers connected by a mall and a hotel. The skyscraper was designed by Helmut Jahn, who also designed buildings such as MesseTurm in Frankfurt, Germany, 50 West Street in New York City, and the Bank of America Tower in Jacksonville, Florida, among many others. The developer of the project was Rouse and Associates, which eventually transformed into Liberty Property Trust, which built both of the Comcast skyscrapers that today dominate the skyline.

As the World Remembers Helmut Jahn, One Liberty Place Lights Up the Skyline

8:00 am on May 10, 2021 By Thomas Koloski

Philadelphia YIMBY often shares exciting and uplifting news regarding the city and its development. However, on May 8th, in Chicago, world-renowned architect Helmut Jahn was tragically killed in a road incident not far from his eponymous firm. According to the press, Jahn was biking near his home, 40 miles away from Chicago, when he was struck by two vehicles and was pronounced dead the next day at 81 years old. The architect was born on January 4, 1940 in Zindorf, Germany, and has designed an incredible amount of buildings between 1974 and 2017. In his lifetime, Jahn has produced unique and awe-inspiring designs throughout the world, which stood out as ahead of their time, and has left a dramatic imprint on the Philadelphia skyline.

Two Liberty Place at 50 South 16th Street in Center City is a 848-foot-tall skyscraper similar in style to the complex’s anchor tower One Liberty Place at 1650 Market Street, with its floor boosted by an extension on the north side of the structure. Designed by Murphy/Jahn and developed by Willard G. Rouse III of Rouse and Associates, the tower was erected in 1988 and stands 58 stories tall. Philly YIMBY looks at the design process through drawings by Helmut Jahn that date to 1986.

Imagining the Philadelphia Skyline with the 1985 Iteration of Liberty Place

8:00 am on March 28, 2021 By Thomas Koloski

On April 5, 1984, Willard G. Rouse of Rouse and Associates announced the proposal of Liberty Place, a complex in Center City that would rise hundreds of feet above the informal height limit set by the 548-foot Philadelphia City Hall. By the next year, Helmut Jahn of Murphy/Jahn Architects finalized the design on One Liberty Place at 1650 Market Street as the design we see today, though Two Liberty Place, The Shops at Liberty Place, and the hotel all differed from their current versions. Today Philly YIMBY takes a closer look at this early iteration of the complex design.

One Liberty Place has been a centerpiece of the Philadelphia skyline since 1987, with a nighttime display that highlights the angled crown and spire. Designed by renowned architect Helmut Jahn and developed by Rouse and Associates, the 945-foot-tall, 61-story tower is part of a complex that includes the similarly-sized Two Liberty Place tower as well as a hotel and a shopping mall.

Designing One Liberty Place, the Tower that Transformed Philadelphia’s Skyline

8:00 am on January 18, 2021 By Thomas Koloski

One Liberty Place at 1650 Market Street is an intricately designed skyscraper has dominated the skyline of Center City for over three decades. Designed by Murphy/Jahn and developed by Rouse and Associates, the tower is clad in a pattern of stone, metal, and glass that rises up to the angled crown and the thin spire. The tower first rose to its final 61-story height in the beginning of 1987, when the top floor was assembled beneath the future spire. Philly YIMBY looks back at the design process by architect Helmut Jahn via drawings from 1984, which show multiple design iterations.

How One Liberty Place Revolutionized the Philadelphia Skyline

8:00 am on January 5, 2021 By Thomas Koloski

In August 1987, the 945-foot-tall One Liberty Place officially opened at 1650 Market Street as Philadelphia’s tallest skyscraper, soaring above the long-held unofficial height limit of 548 feet, set by the tower of City Hall in 1901. This remarkable skyscraper with a fantastical design ultimately led to the city gaining a new cluster of tall and massive skyscrapers that define the skyline to this day. In this feature, Philadelphia YIMBY explores the building’s progress from concept to reality, as well as its tenure as the city’s tallest skyscraper for 31 years.
