Though it has been open for around a decade, Millennium Park already has a legendary reputation in Chicago. The 100,000 square meter complex may have cost the city nearly $180 million to build, but its worth has extended far beyond the price tag. An intimate urban oasis full of welcoming communal space and public sculpture, Millennium Park has become the city’s second most frequented tourist site after Navy Pier. Built on a former rail yard in the middle of downtown, the park boasts Frank Gehry’s Pritzker Pavilion, a sculpture inspired by a drop of mercury by British artist Anish Kapoor, and two 15-meter-tall water fountains made from 18,000 glass bricks that function as video screens. On summer evenings, hundreds of people settle in here with picnics spread across the lawn to listen to the park’s many free concerts. Summer highlights include the Chicago Jazz Festival and the Grant Park Symphony Orchestra, which play free concerts three nights a week.
