BrickFair is a Lego convention and exhibition held annually in the Eastern United States. It was first held in 2008 at Tysons Corner, Virginia by Todd Webb, and in subsequent years, the Virginia convention has been held in Chantilly, typically during the first weekend of August. BrickFair is a four-day event, operating generally Thursday through Sunday. The convention displays Lego models, displays and trains, most often covering more than 100,000 square feet of convention space. BrickFair conventions are also held in New England and the Southeastern United States, with the advent of BrickFair Alabama in 2012 and BrickFair New Hampshire in 2013. BrickFair currently operates in every season and in four East Coast states. BrickFair is believed to be the largest Lego convention in the United States and one of the largest in the world. The Virginia convention usually has approximately 20,000 attendees fill the Dulles Expo Center throughout its public hours, while the Alabama convention has grown steadily in public attendance each year.
