The ruins of Pompeii are located near the modern suburban town of Pompei (nowadays written with one 'i'). It stands on a spur formed by a lava flow to the north of the mouth of the Sarno River (known in ancient times as the Sarnus).Today it is some distance inland, but in ancient times was nearer to the coast. Pompeii is about 8 km (5.0 mi) away from Mount Vesuvius. It covered a total of 64 to 67 hectares (170 acres) and was home to approximately 11,000 to 11,500 people on the basis of household counts.[4] It was a major city in the region of Campania.
