Rosemont is a village in Cook County, Illinois, United States, located immediately northwest of Chicago. As of the 2010 census it had a population of 4,202. The village was incorporated in 1956, though it had been settled long before that. While Rosemont's land area and population are relatively small among municipalities in the Chicago Metropolitan Area, the village is a major center for commercial activity in the region and is a key component of the Golden Corridor. Due to its proximity to several interstates, O'Hare International Airport, and downtown Chicago, it has emerged as a significant edge city and entertainment district, with numerous corporate facilities, millions of square feet of office space, nearly 50 restaurants, 15 hotels, the 840,000-square-foot (78,000 m²) Donald E. Stephens Convention Center (home to numerous conventions and trade shows), the 16,000+ seat Allstate Arena (home to the Chicago Wolves, Chicago Sky, DePaul Blue Demons, and numerous concerts and other live entertainment events), the 4,000+ seat Rosemont Theatre, the 130-store Fashion Outlets of Chicago, the Ballpark at Rosemont (home to an outdoor collegiate-level baseball stadium and 140,000 sq ft indoor sports dome), and the entertainment complex MB Financial Park, which features restaurants, entertainment and a large common area used for summer concerts and ice skating in the winter.
