Top 10 Ancient Ruins in Magna Graecia
Magna Graecia — 'Greater Greece' — was the name given by the Romans to the Greek-colonised coastal regions of southern Italy and Sicily, where the cities founded by migrants from Corinth, Sparta, Rhodes, and other Aegean states from the 8th century BC onwards grew to surpass many of their mother cities in wealth and ambition. The Greeks came seeking agricultural land, metal resources, and trade routes, and what they built in the western Mediterranean represented the full flowering of archaic and classical Greek civilisation on new soil. Philosophers lived and taught here: Pythagoras at Croton, Parmenides at Elea, Empedocles at Agrigentum. Some of the largest temples in the Greek world were built not in Greece itself but in Sicily and southern Italy. Many of these colonial cities were subsequently absorbed by Rome, and the ruins that survive are layered: Greek temples that became Roman temples, Greek harbours that remained active under Roman administration, Greek theatres still used for performances two and a half thousand years after their construction.
1. Paestum, Campania
Paestum (ancient Poseidonia, later Paestum under Rome) contains three of the best-preserved Doric temples anywhere in the world, standing in an open plain south of Salerno in what was once the colony of the Sybarites from around 600 BC. The Temple of Hera I (the 'Basilica'), the Temple of Hera II (the 'Temple of Neptune'), and the Temple of Athena stand in a row that makes their different periods of construction and their evolving proportions immediately apparent — the archaic heaviness of the 6th-century temples giving way to the more refined 5th-century columns of the Temple of Hera II. The site museum is essential and contains the extraordinary Tomb of the Diver, the only complete Greek painted tomb to survive from the classical period, with its symposium scenes and the single diving figure that gives it its name. Paestum is a UNESCO World Heritage Site.
2. Valley of the Temples, Agrigento, Sicily
The Valle dei Templi outside Agrigento is the most spectacular concentration of ancient Greek temples outside of Athens, with seven major temples strung along a ridge above the modern city. Akragas (Roman Agrigentum) was one of the wealthiest cities in the Greek world in the 5th century BC, and its temples reflected that prosperity. The Temple of Concordia, built around 440 BC, is the best-preserved Greek temple in existence after the Hephaisteion in Athens — its columns still stand complete and the pediment is largely intact, in part because it was converted into a church in the 6th century AD. The Temple of Hera (Juno Lacinia), the Temple of Heracles, and the remains of the enormous Temple of Zeus Olympios, which if completed would have been the largest temple in the Greek world, complete an extraordinary ensemble. The valley is a UNESCO World Heritage Site.
3. Selinunte, Sicily
Selinunte on the southwestern coast of Sicily was one of the most ambitious of the Sicilian Greek colonies, with a series of massive temples on two hilltops flanking the ancient city. The city was sacked by Carthage in 409 BC and never fully recovered, which paradoxically preserved the ruins from later overbuilding. The largest temple (known as Temple G), dedicated possibly to Apollo or Zeus, was never completed — its half-finished columns and massive worked drums collapsed in antiquity, and the resulting jumble of giant stone blocks lying exactly where they fell gives Selinunte an atmosphere of frozen catastrophe unlike any other ancient site. Temple C on the acropolis has been partially re-erected and its metopes — carved relief panels showing Perseus beheading Medusa and Heracles with the Cercopes — are displayed in the Palermo archaeological museum.
4. Segesta, Sicily
Segesta in northwestern Sicily was not a Greek colony but an Elymian city that adopted Greek architectural forms as a statement of cultural aspiration and political legitimacy. The Doric temple at Segesta, built around 420 BC, was never completed — its columns lack fluting, and the cella was apparently never built — yet it stands in near-perfect condition on a hillside above a valley, its isolation and incompleteness giving it a peculiar melancholy. The Greek theatre, carved from the hillside of Monte Barbaro, dates from the 3rd century BC and offers panoramic views across the valley toward the coast. Both temple and theatre are well preserved and are among the most visited ancient sites in Sicily. The site is accessible from Trapani and Palermo.
5. Metapontum, Basilicata
Metapontum (Metaponto) on the gulf of Taranto in Basilicata was one of the richest agricultural colonies of Magna Graecia, its territory in the Basento valley producing wheat surpluses that funded monumental building in the 6th and 5th centuries BC. The philosopher Pythagoras spent his final years here after being expelled from Croton, and the site of his school was pointed out to travellers for centuries. The most visible remains are the Tavole Palatine — fifteen standing Doric columns of a Hera temple, dating to around 530 BC — and the grid of the ancient city is clearly traceable in the modern agricultural landscape. The Metapontum Archaeological Museum presents finds from the city and from Braida di Vaglio, an important inland sanctuary site. The beaches near the ancient city are a draw for summer visitors.
6. Locri Epizephyrii, Calabria
Locri Epizephyrii near the modern town of Locri in Calabria is one of the most historically significant of the Greek western colonies, credited by ancient sources with being the first Greek city to write down its laws — the Locrian code of Zaleucus, around 660 BC, a foundational moment in the history of written law. The archaeological site is extensive but not well developed for tourists; the most accessible elements are the remains of a sanctuary of Persephone that produced a remarkable series of terracotta pinakes (votive tablets) depicting the goddess and her myths. These pinakes, now in the Reggio Calabria museum, represent some of the finest archaic and classical terracotta art from Magna Graecia. The site museum in Locri holds supplementary material.
7. Sybaris and Thurii (Sibari), Calabria
Sybaris, near modern Sibari in Calabria, was proverbially the wealthiest and most luxurious city in the Greek world — the source of the word 'sybaritic' — before its destruction by rival Croton in 510 BC. The city was subsequently rebuilt as the pan-Hellenic colony of Thurii in 444 BC, with the involvement of Pericles and the philosopher Protagoras. The overlapping archaeology of three cities (Sybaris, Thurii, and the Roman Copia built on the same site) makes this one of the most complex stratigraphic challenges in Italian archaeology. The subsoil is waterlogged, preserving organic materials but complicating excavation. The Sybaris Archaeological Museum presents finds from all three phases. Ancient Sybaris remains largely unexcavated beneath the surrounding farmland.
8. Croton (Crotone), Calabria
Croton was the most powerful city in Magna Graecia in the 6th and 5th centuries BC, defeating Sybaris in 510 BC and long dominant militarily in the toe of Italy. Pythagoras established his influential philosophical brotherhood here around 530 BC, and Croton was famous for its athletes — sixteen Olympic winners in a generation, an astonishing record attributed to Pythagorean dietary and exercise regimes. The great Hera sanctuary at Cape Lacinio, about 11 kilometres from modern Crotone, preserves a single standing column of the Doric temple, a landmark visible from the sea for millennia. The Museo Nazionale di Crotone holds finds from the sanctuary and the city, including votive material and an important collection of coins.
9. Herakleia (Policoro), Basilicata
Herakleia was founded around 433 BC by the joint efforts of Tarentum and Thurii as a neutral territory between their competing spheres of influence. The site near modern Policoro produced one of the most important legal documents of the Greek world — the Heraklean Tables, bronze tablets inscribed with regulations for public land use around the city, dating to the late 4th century BC. The Museo Nazionale della Siritide at Policoro holds these bronze tablets along with extraordinary finds from Herakleia and from earlier occupation of the site, including archaic terracottas from a sanctuary that predates the Greek colony. The museum is one of the best-kept secrets of southern Italian archaeology.
10. Elea (Velia), Campania
Elea (Latin Velia) near Ascea in Campania was founded by Phocaean Greeks around 540 BC, exiles who had left their Ionian homeland when Persia conquered it. It became famous as the home of the Eleatic philosophical school: Parmenides, who argued that reality is one and changeless, and Zeno, whose paradoxes challenged Greek conceptions of motion and infinity. The visible ruins include a well-preserved Doric temple on the acropolis (the so-called 'Porta Rosa', a vaulted arch of the 4th century BC, is the only surviving Greek round arch in existence), residential quarters, and city walls. The site is set in attractive hill country near the Cilento coast. Elea is a UNESCO World Heritage Site jointly with Paestum and the Certosa di Padula.
Southern Italy and Sicily are well connected by air to major European hubs and by rail from Rome and Naples. The Sicilian sites cluster in the western half of the island and can be covered in several days based at Palermo or Agrigento. Calabrian and Campanian sites require a car. The best seasons are spring (April–May) and autumn (September–October), when temperatures are comfortable and crowds manageable.
