River City is a mixed-use building at 800 South Wells Street in Chicago, Illinois. It was designed by Bertrand Goldberg, to whose Marina City it bears clear affinities, and was completed in 1986. The S-shaped structure located in the South Loop neighborhood of Chicago alongside the Chicago River houses a 70 slip marina, indoor parking, commercial space, apartments (later converted to condominiums), and even a preschool. River City was originally conceived on a much larger scale.
