Marina City is a mixed-use residential-commercial building complex in Chicago, Illinois, United States, North America, designed by architect Bertrand Goldberg. The multi-building complex opened between 1963 and 1967 and occupies almost an entire city block on State Street on the north bank of the Chicago River on the Near North Side, directly across from the Loop. Portions of the complex were designated a Chicago Landmark in 2016.
The complex consists of two 587-foot (179 m), 65-story apartment towers, opened in 1963, which include physical plant penthouses. It also includes a 10-story office building (now a hotel) opened in 1964, and a saddle-shaped auditorium building originally used as a cinema. The four buildings, access driveways, and a small plaza that originally included an ice rink are built on a raised platform next to the Chicago River. Beneath the platform, at river level, is a small marina for pleasure craft, giving the structures their name.
