In remote times, the island of Capri was joined to the surrentine peninsula. Neolithic and the Bronze age artefacts have been found in the "Grotta delle Felci". The remains of the ramparts of a seaside settlement and the so-called "Scala Fenicia", connecting this settlement to one lying further uphill, date from Greek times. The actual residential use of Capri, however, begins with the emperors Augustus and Tiberius. The better preserved sites, viz. Villa Iovis and "Palazzo a Mare" in Capri, Villa Damecuta in Anacapri, go back to this period. In the first, which lies on the promontory delimiting Marina Grande, the remains of the imperial, servant and thermal quarters, lying around the imposing water reservoirs, are still visible. The vestiges of the "Palazzo a Mare" are not as well preserved, having been incorporated into modern buildings, with the exception of the seaside quarter, still partially visible in the modern "Bagni di Tiberio". At the north-west extremity of the island, one can admire the residential quarters of the Villa Damecuta, which has not been explored systematically up to now. The "Grotta Azzurra" ("Blue Cave"), an intriguing Roman nymphaeum where statues have been found, was possibly used as the moorings to a villa probably connected with the ruins visible in the area of Gradola. The so-called "Grotta dell’Arsenale" ("Cave of the Arsenal") near Marina Piccola was probably also a nymphaeum, while the "Grotta di Matromania" was a seat of the cult of the Magna Mater.
