Why go
The city's position on a volcanic plain between the Bay of Naples, the Sarno valley, and Mount Vesuvius change how the excavated city makes sense. Pompeii stood on raised volcanic ground above the Sarno plain, close to routes linking inland Campania with the Bay of Naples.
The full story
Pompeii stood on raised volcanic ground above the Sarno plain, close to routes linking inland Campania with the Bay of Naples. The setting supported farming, trade, and movement while also placing the city within Vesuvius's volcanic system. Ancient shorelines and the river did not match the modern landscape exactly, so the ruins can feel farther from water than their commercial history suggests. The slope is subtle inside the walls but becomes clear near gates and viewpoints. Water distribution also followed elevation: the Castellum Aquae stood high in the north, feeding tanks, fountains, baths, and selected houses. Keep the wider geography in mind as you move. The city was connected to fields, villas, roads, tombs, river traffic, and coastal exchange rather than sealed inside its walls.
