Chicago Water Tower

The Chicago Water Tower is a Chicago, Illinois landmark in downtown Chicago along the Magnificent Mile of North Michigan Avenue. Located on the doorsteps of Loyola University Chicago, the Chicago Water Tower is listed on the National Register of Historic Places and serves as the Chicago Convention and Tourism Bureau Visitor's Welcome Center.

Popularly claimed to have been the only surviving structure after the Great Chicago Fire of 1871, the Chicago Water Tower was built in 1869 by architect William W. Boyington. While it was one of the few buildings within the fire district to survive, much of the city south of the Chicago River survived, including the home of Catherine O'Leary, in whose barn the fire is reputed to have begun.
