Pompeii: A city buried under volcanic ash

It flourished as a city in the Roman Empire, but was buried under volcanic ash after the eruption of Mount Vesuvius. The entire Pompeii area is a World Heritage Site. The ruins are well preserved, so it's easy to imagine what life was like back then. You can't enter without a guide, so you need to arrange one in advance. Address: Pompeii #World Heritage Site
