Millennium Park is the newest park in Chicago even though the original plans were created in 1901.

The park is in the northern part of Grant Park. The main attractions of the park include the Pritzker Pavilion, which was made by Frank Gehry, the man who designed the Guggenheim Museum. Cloud Gate, a 3-story "bean" has become one of the most popular sculptures in Chicago. The Crown Fountain has giant LED video screens that show pictures of Chicagoans in the waterfall. Overall, Millennium Park has a futuristic feel to it.
