Below the rumbling volcano of Mt Vesuvius stand the ruins of Pompeii, an ancient Roman city preserved in time by the eruption in A.D. 79. Excavations have revealed the remains of houses, markets, baths, temples, theaters, streets scarred by the tracks of chariots, and human remains. Visitors can tour the site, walk along the old streets, and see the engineering used by Romans over 2000 years ago.
