The St. Regis Chicago, formerly Wanda Vista Tower, is a 101-story, 1,198 ft (365 m) supertall skyscraper in Chicago, Illinois.Construction started in August 2016, and was completed in 2020. Upon completion it became the city's third-tallest building at 1,198 ft (365 m), surpassing the Aon Center. It is the tallest structure in the world designed by a woman. It forms a part of the Lakeshore East development and overlooks the Chicago River near Lake Michigan.
Designed by architect Jeanne Gang and her architectural firm, Studio Gang Architects, the St. Regis complements the design of the nearby Aqua skyscraper, also designed by Gang, as the two tallest structures in the world designed by a woman. Initially a joint project between Magellan Development Group and Chinese based Wanda Group, the skyscraper cost nearly $1 billion to construct. Magellan bought the project entirely in 2020, and then partnered with St. Regis Hotels & Resorts, which will open the hotel portion in 2022.
