Pompeii was a thriving ancient Roman city of 20,000 residents, buried by Mount Vesuvius in 79 AD under up to 16 feet of volcanic ash. About 2,000 people perished. Hidden for over 1,500 years, it was rediscovered in 1748. Only two-thirds of the 150-acre site has been excavated. Today, over 4 million tourists visit annually.

Pompeii is an ancient Roman city near the Bay of Naples. Once a lively and wealthy place, it was a popular retreat for rich Romans as far back as the 8th century BC. In 79 AD, Mount Vesuvius erupted, covering Pompeii in thick layers of ash and rock. For over 1,500 years, it remained hidden until rediscovered in the 1700s.

24 Fascinating Facts About Pompeii and Mount Vesuvius

Knowing about Pompeii beforehand will help you appreciate its ruins more deeply. Here are 24 fascinating facts about Pompeii and Mount Vesuvius.

1. Pompeii was once a thriving city

Pompeii had around 20,000 residents, filled with markets, grand villas, and lively streets. In August 79 AD, Mount Vesuvius — just 10 km away — erupted, covering the city in up to 16 feet of volcanic ash. Most people escaped, but around 2,000 perished.

2. A 2,000-year-old letter details the eruption

Pliny the Younger witnessed the eruption and described it in a letter, comparing the volcanic cloud to a Mediterranean pine tree. His uncle, Pliny the Elder, died while trying to rescue people. This account remains one of the most valuable eyewitness records in history.

3. Vesuvius’ eruption created geological terminology
