The historic heart of Valencia and the prettiest square in the city. Three buildings hem it in: the Gothic apse of the cathedral, the orange-domed Basilica of Our Lady of the Forsaken, and the Generalitat palace on the west side. The fountain in the middle is the standard meeting point and a good place to watch the world go by with an horchata or a beer.
Time your visit for Thursday at noon to see the Tribunal de las Aguas — the medieval water court still convenes outside the Apostles' Door of the cathedral to settle disputes between local irrigators. It is a UNESCO Intangible Heritage practice and the oldest justice institution in Europe still in operation.
