Pompeii is in Campania, Italy, not far from Naples. Its major attraction is the ruined ancient Roman city of the same name, which was engulfed by Mt. Vesuvius in AD 79. This is a UNESCO World Heritage Site. featuring the main roads, the Cardo Maximus is in Red and the Decumani Maximi are in green and dark blue. The southwest corner features the main forum and is the oldest part of the town.
Romans took control of Pompeii around 200 BC. On August 24, 79 AD, Vesuvius erupted, burying the nearby town of Pompeii in ash and soot, killing 20,000 people, and preserving the city in its state from that fateful day. Pompeii is an excavation site and outdoor museum of the ancient Roman settlement. This site is considered to be one of the few sites where an ancient city has been preserved in detail - everything from jars and tables to paintings and people was frozen in time, yielding, together with neighbouring Herculaneum which suffered the same fate, an unprecedented opportunity to see how the people lived two thousand years ago.
This is a walking site only. There are a few bicycles for rent, but the surfaces make them rather impractical. Walking the old Roman stone roads can be quite exhausting, especially in the heat of summer with loads of fellow tourists about.
