1800 N. Clybourn was an enclosed shopping center located at 1800 N. Clybourn Ave. in the Clybourn Corridor area of Lincoln Park, Chicago. The building was once a factory making springs and later Turtle Wax, which was converted to a three-level enclosed specialty shopping center that retained the structure's wood beams and brickwork. At its opening, developer Tem Horwitz described it as "an industrial environment with the atmosphere of a traveling fair come to town." News reports pointed out the interior's exuberant architecture and unconventional merchandising plan, and that only half its 40 spaces were leased at its opening.
