The Grain Exchange Room located in the Mackie Building, showcases beautiful “Simple Italian” architecture, soaring ceilings, hand painted frescoes, gold leaf and over 10,000 sq. feet of usable event space in an outstanding and historical location.
The three story “cathedral of commerce” was closely linked with the early commercial history of Milwaukee, when for a brief time, the city was the world’s largest primary wheat market for trading, exporting and inspecting grain. Milwaukee’s lake port was near vast acres of wheat so the Milwaukee Grain Exchange made its home in the Chamber of Commerce building, inventing and utilizing the very first octagonal trading pit.
