For history buffs, a visit to Campania is not complete without seeing the ancient ruins of Paestum. Founded by Greek colonists around 600 BC as Poseidonia, it was eventually taken over by the Romans in 273 BC when the name was latinized to Paestum. A visit to the ruins to stroll past the incredibly well-preserved temples and see the top-notch collection at the Museo Nazionale is a great day trip from the Amalfi Coast or Naples.
The archaeological ruins can be reached via train as the Paestum train station (Stazione di Paestum) is located about 800 yards from the ruins. Access can be gained through the perfectly preserved archway Porta Sirena, or—if driving—through the northern gate of Porta Aurea.
