Archaeologists in southern Italy have discovered ancient warrior helmets and the ruins of a painted brick wall at a site that might have been a forerunner of a temple dedicated to the goddess Athena, officials said Tuesday.

Italian Culture Minister Dario Franceschini said the remains dug up at the popular tourist site of Velia were found on what had been an acropolis of one of Magna Graecia’s most important cities. Velia is 40 kilometers (25 miles) southeast of Paestum, a much-visited site of ancient Greek temples.
