Pompeii- The city of Pompeii is a partially buried Roman town-city near modern Naples in the Italian region of Campania. It 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. The structure of whole city and the exact position of the person was in when they died are still can be seen.
Herculaneum, Pompeii sister city, also buried in the eruption. Was hermetically sealed by the ash and lava so many items such as bone and wood were preserved, which was not the case with Pompeii. However, there is a modern city above herculaneum, so only about 25% has been excavated.
