This aesthetically stunning complex occupies a massive 350,000-sq-metre swath of the old Turia riverbed. It’s occupied by a series of spectacular buildings that are mostly the work of world-famous, locally born architect Santiago Calatrava. The principal buildings are a majestic opera house, a science museum, a 3D cinema and an aquarium. Calatrava is a controversial figure for many Valencians, who complain about the expense and various design flaws. Nevertheless, if your taxes weren't involved, it's awe-inspiring and pleasingly family-oriented.

　　The promenades and pools around the buildings make for pleasant strolling and you can hire bikes, paddleboards and various other contraptions to enjoy them.
