Stabiae was an ancient city situated near the modern town of Castellammare di Stabia and approximately 4.5 km southwest of Pompeii. Like Pompeii, and being only 16 km (9.9 mi) from Mount Vesuvius, it was largely buried by tephra ash in 79 AD eruption of Mount Vesuvius, in this case at a shallower depth of up to 5 m.

Castellammare di Stabia is a comune in the Metropolitan City of Naples, Campania region, in southern Italy. It is situated on the Bay of Naples about 30 km (19 mi) southeast of Naples, on the route to Sorrento.
