The City of Arts and Sciences (Valencian: Ciutat de les Arts i les Ciències, Spanish: Ciudad de las Artes y las Ciencias) is an entertainment-based cultural and architectural complex in the city of Valencia, Spain. It is the most important modern tourist destination in the city of Valencia. The City of the Arts and the Sciences is situated at the end of the old riverbed Turia. Turia became a garden in 1980, after the bypass of the river by the great flood of Valencia in 1957. Designed by Santiago Calatrava and Félix Candela, the project underwent the first stages of construction in July, 1996 and the finished "city" was inaugurated April 16, 1998 with the opening of L'Hemisfèric. The last great component of the City of the Arts and the Sciences, El Palau de les Arts Reina Sofía, was presented in October 9, 2005, Valencian Community Day.
