Sinuessa

Sinuessa was a Roman colony founded in 296 BC on the Tyrrhenian Sea coast of northern Campania, Italy, near the mouth of the Volturno River, to protect allied territories during the Third Samnite War. Situated on the Via Appia at the last point where the great highway touched the coast, the city prospered as a port and trading post. Its nearby thermal springs (Aquae Sinuessanae) were renowned for curative properties, mentioned by Livy during the Second Punic War and frequented by Emperor Claudius. Archaeological remains include aqueducts, bath structures, and coastal fortifications near modern Sessa Aurunca. The city declined after warfare and natural disasters, with the population gradually shifting to higher ground inland.
