Chicago is the largest city by population in the state of Illinois and the American Midwest. It is a dominant center of finance, industry and culture in the region. The city, for much of its history, has been known informally as America's "Second City." It is currently ranked as the third-most populous city in the United States after New York and Los Angeles, with a population of nearly 3 million people. Chicago attracted a combined 44.2 million people in 2006 from around the nation and abroad. Upscale shopping along the Magnificent Mile, thousands of restaurants, as well as Chicago's eminent architecture, continue to draw tourists. The city is the United States' third-largest convention destination. Most conventions are held at McCormick Place, just south of Soldier Field. Navy Pier, 3,000 feet (900 m) long, houses retail, restaurants, museums, exhibition halls, and auditoriums. Its 150-foot (46 m) tall Ferris wheel is north of Grant Park on the lakefront and is one of the most visited landmarks in the Midwest, attracting about 8 million people annually. The historic Chicago Cultural Center (1897), originally serving as the Chicago Public Library, now houses the city's Visitor Information Center, galleries, and exhibit halls. The ceiling of Preston Bradley Hall includes a 38-foot (11 m) Tiffany glass dome.
