The Blue Cross-Blue Shield Tower is a "unique combination of a build-to-suit headquarters and a multi-tenant office tower in downtown Chicago" (ctbuh).

The Blue Cross-Blue Shield Tower contains 57 stories of offices, housing about 40 health insurance companies.

"The best views of this building are actually from the back. And at night. This is how you can appreciate the structure of the building. It features a massive central atrium that is clearly visible through the glass in the darkness. You can sit in Lake Shore Park and watch the internal elevators whiz up and down the edges of the atrium serving the workers toiling long into the night. That atrium is surrounded on three sides by banks of offices. The arrangement is similar to the classic light well common in many Chicago buildings built around the turn of the 20th century. People in the offices are able to get light from all sides, even if they are deep within the center of the structure" (Chicago Architecture).
