Santiago Calatrava Valls (Valencian pronunciation: [santiˈaɣo kalaˈtɾava ˈvaʎs], born 28 July 1951) is a Spanish architect, sculptor and structural engineer whose principal office is in Zürich, Switzerland. He has offices in Zürich, Paris, Valencia, and New York City (where he now resides).
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 Arts and Sciences is situated at the end of the former riverbed of the river Turia, which was drained and rerouted after a catastrophic flood in 1957. The old riverbed was turned into a picturesque sunken park.
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 Arts and Sciences, El Palau de les Arts Reina Sofia, was presented on October 9, 2005, Valencian Community Day.
