The original model of the Millennium Monument was the starting point of the Peristyle appearance in Chicago. To this day, it is said to not compare to the once "commanding presence" that once stood in its place, before being demolished and replaced with an underground parking garage. The new monument was downsized by approximately 15% to accommodate a wheel-chair ramp for the disabled in a tight space. It also includes a "classical" take on the original, incorporating a fountain at the base of the limestone, Doric, column monument. The monument, despite being relatively small in comparison to the rest of Grant Park, makes its presence known as the central focus to shape Wrigley Square and the surrounding landscape. Wrigley Square is unique for its fountain that, unlike Buckingham Fountain, which is fenced off, remains open with a circular ledge to allow park-goers the freedom to sit next to the open water to enjoy the atmosphere.
