Park Tower is a skyscraper located at 800 North Michigan Avenue in Chicago, Illinois. Completed in 2000 and standing at Script error: No such module "convert". tall with 70 floors — 67 floors for practical use, it is the twelfth-tallest building in Chicago, the 43rd-tallest building in the United States, and the 83rd-tallest in the world by architectural detail. It is one of the world's tallest buildings to be clad with architectural precast concrete (the Transamerica Pyramid Building in San Francisco is taller). It is one of the tallest non-steel framed structures in the world—it is a cast-in-place concrete framed structure. This building was originally intended to be Script error: No such module "convert". tall. But later, the ceiling heights were increased allowing it to reach Script error: No such module "convert"..

The building occupies a footprint of Script error: No such module "convert".. Because of the small footprint and the fact that it is a non-steel-framed concrete building, this is the first building in the US to be designed with a tuned mass damper from the outset. While other skyscrapers in America have anti-sway systems, they were always added later. A tuned mass damper counteracts wind effects on the structure. (The 300-ton damper is a massive steel pendulum hung from four cables inside a square cage.) Because of its massive weight, the damper has inertia that helps stabilize the building from swaying in the wind.
