Sybil's cave

At the upper side of the Crypta Romana, on the Cumae hill and on a more elevated level, one can find
the Greek / Roman tunnel Antro della Sibilla (Sybil’s cave, 130 m long and 5 m high) which was also
supplied with (three) reservoirs with a common capacity of 130 m3, probably to supply the fleet in
the nearby harbour.
