Valencia Cathedral is one of the city’s most important landmarks, an impressive monument that offers a unique insight into Valencian history and Gothic architecture (although it retains elements from different periods, from Romanesque to Baroque). It was founded in the 13th century and built on the site of an ancient mosque that was originally a Roman temple. Inside, you can admire the great central nave with its Gothic arches and vaults, the Renaissance frescoes on the high altar that were hidden for centuries, the famous arm of Saint Vincent and, of course, the chalice that, according to tradition, Jesus used during the Last Supper: the Holy Grail.
