The ancient city buried under volcanic ash after the eruption of Mount Vesuvius in 79 A.D. is Pompeii. This catastrophic event preserved the city in time, providing invaluable insights into Roman life, culture, and urban planning. The ash created a protective layer that encased buildings, artifacts, and the remains of its inhabitants. Archaeological excavations beginning in the 18th century revealed well-preserved structures, frescoes, and everyday items, offering a glimpse into the lives of ancient Romans. Pompeii serves as a key archaeological site, showcasing the technology, art, and social dynamics of the Roman Empire before its tragic destruction.
