La Almoina

Beneath the square just east of Valencia’s cathedral, the archaeological remains of the kernel of Roman, Visigoth and Islamic Valencia shimmer through a water-covered glass canopy. Head downstairs for an impressively excavated, atmospheric melange of Roman baths, forum buildings and a factory, as well as bits of the Moorish alcázar (fortress) and a royal cemetery. Later remains come from a building erected on this square as a hospital for the poor. Get the audio guide: it's tough to interpret otherwise.
