The first thing to know about Cumae is that it’s an out-of-the way site that’s not easy to get to, nor well served by public transport. Most days, it’s a very quiet place to have a wander and it’s lacking in any real services for tourists. There’s a lot of walking involved with steep grades, but the views are compensatory.
These are all good reasons to visit the first Magna Graecia colony on mainland Italy, an 8th century BC acropolis built by the Euboean Greeks. Even more so, however, is the trapezoidal shaft known as the Antro della Sibilla, the cave, according to Virgil, where the Cumaean Sibyl wrote her oracles and prophesied the glorious future of Rome. Unfortunately, it’s been closed to the public for some time, but you can still get a good look into the cave from the outside.
Venture further up to find the remains of the Temple of Apollo and even further up, the remains of the Temple of Jupiter and those compensatory views. Artifacts found at Cumae are on display at the Campi Flegrei Archaeological Museum at Baia Castle.
