Plensa was born in Barcelona, Catalonia and studied art there, in the "Llotja" School and in the Escola Superior de Belles Arts de Sant Jordi. His works include the Crown Fountain at Millennium Park in Chicago, Illinois, United States.[2] It opened in July 2004.[3][4] The fountain is composed of a black granite reflecting pool placed between a pair of glass brick towers. The towers are 50 feet (15 m) tall,[3] and they use light-emitting diodes (LEDs) to display digital videos on the inward faces.
