About Chicago, United States
Essential information for your London Heathrow to Chicago trip.
Chicago is America's architectural showpiece, the birthplace of the skyscraper and home to a deep-dish pizza that inspires fierce debate. The Windy City's world-class museums, blues and jazz heritage, and stunning lakefront make it one of the most underrated major cities in the US.
Chicago reversed the flow of the Chicago River in 1900 using a series of canal locks, an engineering feat that sent the river flowing away from Lake Michigan.
