The Necropolis of Pantalica in southeast Sicily is a collection of cemeteries with rock-cut chamber tombs dating from the 13th to the 7th centuries BC. There are thought to be over 5000 tombs, although the most recent estimate suggests a figure of just under 4000. They extend around the flanks of a large promontory located at the junction of the Anapo river with its tributary, the Calcinara, about 23 kilometres northwest of Syracuse. Together with the city of Syracuse, Pantalica was listed as a UNESCO World Heritage Site in 2005.
Pantalica is located on a limestone promontory surrounded by a deep gorge formed by the Anapo and Calcinara rivers between the towns of Ferla and Sortino in south-eastern Sicily. In addition to its archaeological interest it is an important nature reserve (Riserva Naturale Orientata Pantalica), with a variety of local flora and fauna and natural caves (notably the Grotta dei Pipistrelli (Bat cave)). Various pathways facilitate visitor access, including a disused railway track (dismantled in 1956) along the Anapo valley bottom. The promontory can be accessed directly with a car from Ferla, or by walking down the old mule track from the parking place on the road from Sortino and crossing over the Calcinara stream.
Pantalica evidently flourished for about 600 years, from about 1250 to 650 BC. The current name of the site probably dates from the Early Middle Ages or Arab period. The ancient name of the site is uncertain, but is associated by some archaeologists with Hybla, after a Sicel king named Hyblon, who is mentioned by Thucydides in connection with the foundation of the early Greek colony at Megara Hyblaea in the year 728 BC. For several centuries before Greek colonization, Pantalica was undoubtedly one of the main sites of eastern Sicily, dominating the surrounding territory, including subsidiary settlements. By about 650 BC, however, it seems to have been a victim of the expansion of the city of Syracuse, which established an outpost at Akrai (Palazzolo Acreide) at this time. Nevertheless, it was still occupied during classical antiquity, since finds of the 4th-3rd centuries BC (Hellenistic period) are attested, as well as during the late antique or Byzantine periods. After the 12th century it was probably largely deserted, and overshadowed by Sortino.
The remains visible today consist mainly of numerous prehistoric burial chambers cut into the limestone rock, sometimes provided with a porch or short entrance corridor in front of the burial chamber, originally sealed with stones or a slab. There are also some larger rock-cut houses of uncertain date (often said to be Byzantine, but possibly of earlier origin). The so-called anaktoron, or princely palace, located near the top of the hill, is also controversial. Thought by some archaeologists originally to have been a Late Bronze Age building, inspired by palatial buildings of the Greek (Mycenaean) Bronze Age, it was more certainly occupied in the Byzantine period. The remains of a large moat, cut into the limestone, are clearly visible at Filiporto (on the western side of the promontory, nearest to Ferla). This probably dates to the 4th century BC and represents a defensive work of Greek military design, possibly in line with a policy of Dionysius of Syracuse, designed to secure allied sites in the hinterland. There are also three small Medieval rock-cut chapels popularly called the Grotta del Crocifisso (near the North cemetery), Grotta di San Nicolicchio (on the southern side) and Grotta di San Micidario (at Filiporto),which preserve very faint traces of frescoes and attest the presence of small monastic communities.
The so-called Anaktoron (a Mycenaean princely palace) on the top of the hill is a multi-roomed building of large blocks, with various rectangular rooms, excavated in the 19th century by Paolo Orsi. Its origins are obscure (see above) but it was certainly used in the Byzantine period, as attested by roof tiles and pottery. Since no other prehistoric houses have been found on the hilltop, which is rather eroded, the location of the original prehistoric residential quarters remains uncertain. There may have been various clusters of habitation associated with each major burial zone.
