In 79 AD, the city of Pompeii in Campania, Italy, was covered in 13-20ft of ash and pumice as Mount Vesuvius erupted.
The eruption lasted for more than 24 hours, starting on the morning of the *24th August with the first waves of hot ash, pumice, rock fragments and volcanic gas reaching Pompeii around midnight.
Paintings of Pompeii were briefly discovered in 1599, but it wasn’t until 1738 when foundations were being laid for a summer palace for the King of Naples (Charles of Bourbon – bet he liked a drink) that the rediscovery of Pompeii really began with a purposeful excavation beginning in 1748.
As with any tourist site in the summer holidays, get there early (to avoid crowds and the heat). I didn’t get the audio guide but people I spoke to highly recommended it.
When visited: July (it was busy)
