Marina City is a
mixed-use residential/commercial building complex that occupies an entire
city block on
State Street in
Chicago,
Illinois. It sits on the north bank of the
Chicago River in
downtown Chicago, directly across from the
Loop district. The complex consists of two
corncob-shaped, 587-foot (179 m), 65-story towers, which include five-story elevators and physical plant penthouses. It also includes a saddle-shaped auditorium building, and a mid-rise hotel building, all contained 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. Designed by
Bertrand Goldberg, Marina City was the first building in the United States to be constructed with
tower cranes.
