Pompeii ( ; Latin: [pɔmˈpei̯.iː]) was a city in what is now the municipality of Pompei, near Naples, in the Campania region of Italy. Along with Herculaneum, Stabiae, and many surrounding villas, it was buried under 4 to 6 m (13 to 20 ft) of volcanic ash and pumice in the eruption of Mount Vesuvius in 79 AD.

Largely preserved under the ash, Pompeii offers a unique snapshot of Roman life, frozen at the moment it was buried, as well as insight into ancient urban planning. It was a wealthy town of 10,000 to 20,000 residents, including businesswomen at the time it was destroyed. It hosted many fine public buildings and luxurious private houses with lavish decorations, furnishings and artworks, which were the main attractions for early excavators; subsequent excavations have found hundreds of private homes and businesses reflecting various architectural styles and social classes, as well as numerous public buildings. Organic remains, including wooden objects and human bodies, were interred in the ash; their decay allowed archaeologists to create moulds of figures in their final moments of life. The numerous graffiti carved on outside walls and inside rooms provide a wealth of examples of the largely lost Vulgar Latin spoken colloquially at the time, contrasting with the formal language of classical writers.

Pompeii remained largely undisturbed until its rediscovery in the late 16th century. Major excavations did not begin until the mid-18th century, which marked the emergence of modern archaeology. Initial efforts to unearth the city were haphazard or marred by looting, resulting in many items or sites being damaged or destroyed. By 1960, most of Pompeii had been uncovered but left in decay; further major excavations were banned or limited to targeted, prioritised areas. Since 2018, these efforts have led to new discoveries in some previously unexplored areas of the city.

Pompeii is a UNESCO World Heritage Site, owing to its status as "the only archaeological site in the world that provides a complete picture of an ancient Roman city". It is among the most popular tourist attractions in Italy, with approximately 2.5 million visitors annually.

Name

Pompeii in Latin is a second declension masculine nominative plural noun (Pompeiī, -ōrum). According to Theodor Kraus, "The root of the word Pompeii would appear to be the Oscan word for the number five, pompe, which suggests that either the community consisted of five hamlets or perhaps it was settled by a family group (gens Pompeia)."

Geography

Pompeii was built approximately 40 m (130 ft) above sea level on a coastal lava plateau created by earlier eruptions of Mount Vesuvius (8 km or 5 mi distant). The plateau fell steeply to the south and partly to the west into the sea. Three layers of sediment from large landslides lie on top of the lava, perhaps triggered by extended rainfall. The city, once by the shoreline, is today circa 700 m (2,300 ft) inland. The mouth of the navigable Sarno River, adjacent to the city, was protected by lagoons and served early Greek and Phoenician sailors as a haven port, later developed by the Romans.
