The Buckingham Fountain, located in Grant Park, is one of Chicago's most popular attractions and one of the largest fountains in the world. It was opened in May of 1927. The four sea horses you see on its sides represent the four states that touch Lake Michigan: Wisconsin, Illinois, Indiana and Michigan. The fountain operates from approximately April 1 to November 1 each year and runs from 10:00 am to 11:00 pm each day. Every hour on the hour for 20 minutes the fountain produces a major water display and the center jet shoots 150 feet into the air. At dusk, the fountain's hourly major water display is accompanied by lights and music. The fountain's water capacity is 1.5 million gallons. Depending on wind conditions, major displays use approximately 14,100 gallons of recirculated water per minute conveyed through 134 jets. The fountain contains 820 lights.
