Inspired by the City of Science and Industry in Paris, the Valencian Autonomous Government created the City of Arts and Sciences, enlisting the talents of architects Santiago Calatrava and Félix Candela to give the Spanish city a modern cultural attraction. Built in a park on the drained riverbed of the Turia River, the first portions of the multi-building attraction opened in 1998. Several additions followed, the most recent being L"Àgora, a covered plaza that opened in 2009 to host concerts, exhibitions, and other events.
