The famous ancient city destroyed by volcanic eruption in 79 AD is Pompeii. Located near modern-day Naples, Pompeii was buried under volcanic ash and pumice when Mount Vesuvius erupted. This catastrophic event preserved the city, allowing archaeologists to gain valuable insights into daily life in ancient Rome. Buildings, frescoes, and artifacts have been remarkably well-preserved, resulting in a unique snapshot of Roman urban life. Pompeii is now a UNESCO World Heritage Site and attracts millions of visitors each year who come to explore its ruins and learn about its historical significance.
