A bit outside the city center of Valencia, you'll find Bombas Gens, a large space with expansive exhibition rooms dedicated to modern art. When we visited, the exhibitions ranged from framed art and photography to large-scale visual installations and light projections.
We loved it. The buildings themselves are beautiful, and we also enjoyed the gardens attached to it. There's a fancy restaurant on the premises, too. And if you want to dive deeper, you can arrange a tour to visit the underground REFUGIO bunkers.
