Copied verbatim from A View on Cities (dot com) Marina City is a complex of two 60-story towers built in 1964 by Bertrand GoldBerg, a student of Mies van der Rohe. It is a lively complex of apartments, recreation facilities, offices, restaurants, banks, a theater and 18 stories of parking space. The complex even boasts a dock at the Chicago River underneath the towers.
The experimental complex was financed by unions who feared that the outflow of people from the cities in the early sixties would lead to a decrease in jobs. Marina city would give an alternative to the villages and small towns, offering everything in a small area.
