VALENCIA
City of Arts and Sciences
The City of Arts and Sciences is an ensemble of six areas in the dry river bed of the now diverted River Turia in Valencia, Spain. Designed by Valencian architect Santiago Calatrava and started in July 1996, it is an impressive example of modern architecture. The "city" is made up of the following, usually known by their Valencian names: El Palau de les Arts Reina Sofía — Opera house and performing arts centre; L'Hemisfèric — Imax Cinema, Planetarium and Laserium; L'Umbracle — Walkway / Garden; El Museu de les Ciències Príncipe Felipe — Science museum; Oceanografic — Open-air aquarium or oceanographic park; Ágora — A versatile space that will allow the holding of varied events.

The Oceanographic Museum
The oceanographic park, created as a leisure, training and research centre, is structured into ten great areas. The marine areas reflect the Mediterranean habitats, the polar oceans - the Arctic and the Antarctic, the islands, the tropical seas, the temperate seas and the Red Sea. Moreover, the park also has a spectacular dolphinarium, an auditorium - within which one can find the Red Sea aquarium - with an area for the mangrove swamps and another for the marshlands, and different garden areas, with more than 80 different plant species.
La Lonja de la Seda
La Lonja de la Seda de Valencia
Built between 1482 and 1533, this group of buildings was originally used for trading in silk (hence its name, the Silk Exchange) and it has always been a centre for commerce. It is a masterpiece of late Gothic architecture. The grandiose Sala de Contratación (Contract or Trading Hall), in particular, illustrates the power and wealth of a major Mediterranean mercantile city in the 15th and 16th centuries.
