Why go
The settlement's Oscan beginnings, Greek and Etruscan contacts, Samnite growth, and early defenses change how the excavated city makes sense. Long before Pompeii became a Roman colony, communities occupied the volcanic terrace above the Sarno plain. Archaeology points to Oscan settlement and sustained contact with Greek and Etruscan centers around Campania.
The full story
Long before Pompeii became a Roman colony, communities occupied the volcanic terrace above the Sarno plain. Archaeology points to Oscan settlement and sustained contact with Greek and Etruscan centers around Campania. The city's early sacred and defensive spaces changed as political power shifted. Samnite-period construction expanded houses and public buildings, while later Roman work often reused earlier foundations. This is why the site does not present one clean architectural date. The Doric Temple, Sanctuary of Apollo, city walls, and irregular street patterns preserve clues to phases that predate the familiar imperial city. Look for differences in masonry and orientation rather than expecting every visible wall to belong to AD 79. Pompeii's earlier centuries explain why some monuments sit at angles or scales that later Roman planners inherited rather than designed from scratch.
