Cloud Gate is a 3-story, 110-ton steel sculpture it is also called as “The Bean” due to its legume-like shape. Cloud Gate is designed by the world-renown artist Anish Kapoor. Cloud Gate is center piece of the AT&T Plaza and is located on top of Park Grill and adjacent to the Chase Promenade.
Cloud Gate is wildly popular, it was privately funded and the total cost was $23 million, which was considerably more than the original estimate of $6 million. The design was inspired by liquid mercury. It measures 66-feet long by 33-feet high.
The sculpture is made of stainless steel plates that create an elliptically-arched, highly reflective work with Chicago’s skyline. When Millennium Park opened in 2004, the grid of welds around each metal panel was visible, so in 2005 workers polished out the seams. Cloud Gate is a highly-polished reflective steel sculpture and its exterior reflects and transforms the city’s skyline.
Visitors are able to walk around and under Cloud Gate's arch to fully experience the majestic nature of the work. One of the features of the cloud gate is the omphalos, which is located in the center of the underside of the sculpture. The omphalos is an indentation, with its mirrored surface it provides multiple reflections of any subject situated directly beneath it when looking up.
Grant Park Music Festival is the nation's only remaining free, municipally-supported, outdoor, classical music series. This Pavilion has a great state-of-the-art sound system, the first of its kind in the country, and it was designed to sound similar to indoor concert hall with digital innovations and enhanced sound so that it can be distributed to enhance sound equally over both the fixed seats and the lawn.
