10Pompeii was a seaside town

The eruption of Mount Vesuvius did more than bury the city in a tomb of ash and pumice: it also changed the landscape.

Evidence of fish in Pompeiian diets, to interpretations of the sea in frescoes, makes it clear that Pompeii used to be on the coast. The pyroclastic blast in 79 A.D. caused the top of Mt. Vesuvius to collapse, transforming today’s version of Pompeii into the landlocked city.
