The city is located 135 miles (217 km) south of Chicago, 124 miles (200 km) west of Indianapolis, Indiana, and 178 mi (286 km) northeast of St. Louis, Missouri. Though surrounded by farm communities, Champaign is notable for sharing the campus of the University of Illinois at Urbana-Champaign with its sister city of Urbana. Thanks to the university and a number of well known technology startup companies, it is often referred to as the hub, or at least a significant landmark, of the Silicon Prairie. Champaign is also the home of Parkland College. Champaign houses offices for seven Fortune 500 companies, and two more are planned to arrive soon.
