L'Oceanografic in Valencia is dedicated to the natural world, here you can explore the seven seas of the world and watch dolphins perform.

L'Oceanogràfic invites us to travel around the planet's main seas and oceans. More than 45,000 examples of 500 different marine species

The park, created as a great leisure, training and research centre, is structured into ten 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 area for the mangrove swamps and another for the marshlands, and different garden areas, with more than 80 different plant species.

The City of Arts and Science in Valencia is fast becoming one of Spain's top tourist attractions.

The Hemesferic was the first building to be completed in 1998 - an extraordinary Calatrava creation resembling a huge eyeball floating above a pool of water. The eye even blinks with the aid of a steel and glass shutter operated by hydraulic lifts. When you've finished drinking in the impossibility of the building's architecture it's well worth taking in a show at the Hemesferic's planetarium or Imax theatre.

The centerpiece of the whole complex is the equally awesome science museum which opened alongside the Hemesferic in 2000. Some people reckon it looks like a Tyrannosaurus Rex skeleton from the outside whilst others see it as the spine of some huge, prehistoric fish. And certainly for many visitors the building itself is the star exhibit despite the many fascinating hands-on science displays contained within it.

Children love the fact that the museum is a far cry from those fusty halls of hallowed ancient artifacts with show cases bedecked with "don't touch" signs. Touching is essential for most of the Felipe museum's exhibits which encourage learning through curiosity and entertainment this is "edutainment" 21 st century style and there are few places in Europe which do it better.

The Palace of the Arts Reina Sofia was the last to be opened in 2005. It has four rooms devoted to art, music and drama perfromances.
