The city of Pompeii is a partially buried Roman town-city near modern Naples in the Italian region of Campania, in the territory of the comune of Pompei. Along with Herculaneum, Pompeii was partially destroyed and buried under 4 to 6 m (13 to 20 ft) of ash and pumice in the eruption of Mount Vesuvius in AD 79.
I remember the National Geographic's article on Pompeii, and since then, I've wanted to go there. In the year 79 AD, Italy's Mt. Vesuvius erupted with superheated ash that rained fiery death on several Roman cities nearby. But none was hit harder than vacation town Pompeii, which was buried in a thick layer of broiling ash in a matter of seconds.
