The aesthetically stunning City of Arts & Sciences occupies a massive 350,000-sq-metre swath of the old Turia riverbed. It’s mostly the work of world-famous, locally born architect Santiago Calatrava. He's a controversial figure for many Valencians, who complain about the expense, and various design flaws that have necessitated major repairs here. Nevertheless, if your taxes weren't involved, it's awe-inspiring stuff, and pleasingly family-oriented.
