Pompeii was recently in the news when a series of collapses of 2,000 year old buildings sparked accusations of mismanagement by the Italian Culture Ministry.
A volcanic eruption in 79 AD buried Pompeii under 6 metres of volcanic ash, preserving much of the city. The archaeological site extends over 76 hectares.
Pompeii is the largest archaeological site in the world. It received 2.2 million visitors in the first 10 months of 2010.
