The Chicago Water Tower is a contributing property in the Old Chicago Water Tower District landmark district. It is located at 806 North Michigan Avenue along the Magnificent Mile shopping district in the Near North Side community area of Chicago, Illinois. The tower was constructed to house a large water pump, intended to draw water from the Lake Michigan; it now serves as a Chicago Office of Tourism art gallery. The Chicago Water Tower is the second-oldest water tower in the United States, after the Louisville Water Tower in Louisville, Kentucky.
The tower, built in 1869 by architect William W. Boyington from yellowing Joliet limestone, is 154 feet (47 m) tall. Inside was a 138 foot (42 m) high standpipe to hold water. In addition to being used for firefighting, the pressure in the pipe could be regulated to control water surges in the area. Together with the adjacent Chicago Avenue Pumping Station, it drew clean water from water cribs in Lake Michigan.
