James R Thompson Center

Completed in 1985, the James R. Thompson Center is a controversial work of contemporary architecture that has at the same time been lauded and heavily criticized.
As the winner of the 1986 Distinguished Building Award of the Chicago Chapter, American Institute of Architects, architect Helmut Jahn was touted as making a “strong, powerful, and important statement” that “broke new ground” in the city of Chicago. Others consider the building, which was given the nickname 'cash register', an impractical monstrosity.

In any case the building is commanding. From its location on the North Loop, it has earned worldwide attention. Massive in size, the James R. Thompson Center reaches 332 feet (100m) into the air and occupies 1,193,163 square feet of space. The building, originally known as the State of Illinois Center, cost $89 million to build.

The structure is a low-block design. The glass-enclosed steel structure, with a curving, sloping façade, boasts 17 stories, with 2 additional floors underground. The exposed steel is red and the cladding bright turquoise, making for a colorful sight.

Inside, you’ll find a soaring cylindrical atrium which extends through the roof to a skylight. Glass elevator shafts project into the atrium as well, and the view of the gigantic Concourse Level from the 72-foot-diameter open cut out of the lobby can be breathtaking.

As the principal state government building in Chicago, the James R. Thompson Center houses most of the state government agencies but also includes a large commercial area that features lots of shops and restaurants. Inside, you’ll also find what’s been dubbed as one of the world’s largest collections of contemporary artwork by Chicago natives. More than 600 works of art make their permanent home at the James R. Thompson Center, ranging from photographs to oil paintings to wood sculptures.

There’s also a 7,500-square-foot Assembly Hall that seats 600, often the site of concerts, theatrical productions, meetings, lectures, and other special events.
