 Plensa 's design of Crown Fountain was unveiled to the public on July 16 – 18 , during the 2004 grand opening celebrations for Millennium Park , which was sponsored by J.P. Morgan Chase & Co . At the time of the unveiling , Crown Fountain , like the nearby Cloud Gate , was incomplete because only 300 of the videos had been refined for public display . It was officially dedicated on July 24 , 2004 as part of a special private fundraising party that raised $ 3 million for the Millennium Park Conservancy fund .
