Both Pompeii and Herculaneum are UNESCO World Heritage sites. They were both covered
in ash from the Vesuvius volcanic eruption in AD79, and have since been excavated
to reveal the wonders that you see today. Pompeii was a commercial town, while Herculaneum
was a holiday resort. The top right and bottom middle photos that are shown here
are of Herculaneum and the other three are of Pompeii.
