Valencia was established by the Greeks and later occupied by the Carthaginians, Romans, Visigoths and Arabs. A 15th century artistic movement here gave the world spectacular paintings, sculptures, and jewels. Today a “City of Arts and Sciences,” Valencia offers visitors remarkable samples of modern architecture, alongside such notable classics as the 13th century Cathedral and Chapel of the Holy Chalice. Built on the site of a mosque which was originally a Roman temple the Chapel contains the chalice which legend says was used by Christ at the Last Supper. For a more historic view, take in the Quart Towers, a former gate of the medieval wall, built in 1444; and Serranos Towers, a former prison surrounded by a moat and built around 1391.
