Millennium Park

• Completed in 2004, the 24.5-acre Millennium Park in downtown Chicago is home to a number of the city's newest landmarks, including the Crown Fountain, a work of Spanish artist James Plensa that consists of a shallow reflection pool with a 50-foot glass tower on either end. Each tower features an LED screen onto which faces of 1,000 Chicago residents are projected. Reminiscent of fountain gargoyles, water appears to flow through the mouths of the faces pictured through outlets in the screens
  
  Also located in Millennium Park is British artist Anish Kapoor's Cloud Gate, a 110-ton elliptical stainless-steel sculpture that reflects Chicago's skyline and the clouds in the sky. A concave chamber beneath the sculpture allows visitors to touch the surface of the sculpture and view distorted reflections of themselves, similar to those produced by fun house mirrors.
  
  Millennium Park is open every day from 6 am to 11 pm Admission is free.
