Right in the heart of Valencia’s beautiful old town, the cathedral—known as La Seu—is made up of a mix of different architectural styles. The central dome and tower are Gothic in style, while the main entrance is baroque and several of the chapels date from the Renaissance period. Inside you’ll find a series of frescoes by renowned Spanish painter Goya (housed in the de Borgia chapel), plus, of course, the chalice itself, kept behind glass in the opulent Capilla del Santo Cáliz near the main entrance.
Guided walking tours of the city regularly stop at the cathedral—and spending time with a local guide is a great way to learn about the Grail mystery. The Holy Grail is sacred, as it’s thought to be the chalice that Jesus drank from at the Last Supper. The chalice has been kept in the cathedral since the 15th century and is recognized by the Vatican. There’s only one other recognized grail relic in existence in the world—the other is a green glass dish known as the Sacro Catino, kept at Genoa Cathedral in Italy.
