The Chicago Architecture Center Auxiliary Board consists of architectural enthusiasts and design professionals interested in Chicago’s architecture.

Founded in 1974, the Auxiliary Board supports the CAC through fundraising and ambassadorship. The Auxiliary Board’s signature event is the annual River Cruise that has raised more than $400,000 for CAC programs. 

Auxiliary Board River Cruise

There’s no better place to be in the summer than Chicago, and every summer the Auxiliary Board River Cruise is the best party on the river. Guests enjoy music, gourmet food and drinks, and world-class architecture from an unmatched view as we take Trip Advisor’s Top Tour in Chicago and kick it up a notch. Funds raised during this event provide aspiring architects and designers the chance of a lifetime through the CAC’s education programs. Each River Cruise has a theme; past ones have included pirates, rodeo, luau, and the 1960's.

Additional events and programs

The Auxiliary Board also creates opportunities for their members with access to some of Chicago’s most exclusive sites. Auxiliary Board events are held throughout the year in spaces that are often not open to the public. Past events have included receptions in newly constructed buildings, hardhat tours of historic renovations and a holiday parties in the homes of Auxiliary Board members.
