Valencia's cathedral was built over the mosque after the 1238 reconquest. Its low, wide, brick-vaulted triple nave is mostly Gothic, with neoclassical side chapels. Highlights are rich Italianate frescoes above the altarpiece, a pair of Goyas in the Capilla de San Francisco de Borja, and…ta-dah…in the flamboyant Gothic Capilla del Santo Cáliz, what's claimed to be the Holy Grail from which Christ sipped during the Last Supper. It's a Roman-era agate cup, later modified, so at least the date is right.
