Brickworld
Brickworld Chicago is a convention for adult fans of LEGO (AFOLs) to display and share their creations made of LEGO bricks. Brickworld consists of both a private convention and a public exposition.
Brickworld's private convention offers workshops, presentations, roundtable discussions, special events and challenges. The event provides an opportunity for fan community to get together and learn from each other. The AFOLs are the main focus of Brickworld. Brickworld occurs annually on the third weekend in June. In 2013 it will be held at the Renaissance Hotel and Convention Center in Shaumburg, IL.
Brickworld also operates several exposition only events around the Midwest and Florida. You can learn more at
