Top 10 Roman Ruins in the Mediterranean
The Roman Empire at its peak encompassed the entire Mediterranean basin — mare nostrum, "our sea" — from Britain to Mesopotamia, from the Rhine to the Sahara. The architectural legacy of this empire is distributed across more than 30 modern nations. The sites listed here were selected for the quality, scale, and state of preservation of their surviving remains, spanning the western and eastern Mediterranean and representing the full range of Roman architectural ambition: city planning, religious architecture, spectacle buildings, military infrastructure, and engineering monuments.
1. The Colosseum, Rome, Italy
The Flavian Amphitheatre, opened in 80 CE under Titus, is the largest amphitheatre ever built, capable of seating 50,000–80,000 spectators for gladiatorial contests, animal hunts, and public executions. Its travertine limestone, brick, and concrete construction reaches 48 metres and features a sophisticated seating arrangement tiered by social class, with 80 arched entrances for rapid egress. Below the arena floor, the hypogeum — a network of tunnels, cages, and lifting mechanisms — has been excavated and is now partly accessible. The Colosseum was stripped of much of its travertine for medieval building projects but remains structurally substantial. Accessible year-round; advance booking strongly recommended.
2. Leptis Magna, Khoms, Libya
Leptis Magna, birthplace of the emperor Septimius Severus (r. 193–211 CE), is the best-preserved large Roman city anywhere in the Mediterranean world. Severus lavished enormous imperial investment on his home city, adding a new forum, a four-way arch, a new harbour, and a colonnade street, all completed within a decade and still surviving to considerable height. The Hadrianic Baths are among the largest in the Roman world; the theatre (first century CE) is almost completely intact. The site is a UNESCO World Heritage Site; Libya's political instability since 2011 has made access difficult and conservation funding precarious, but the monuments themselves survive because centuries of sand burial limited looting of building stone.
3. Jerash (Gerasa), Jordan
Jerash, in northern Jordan, is one of the best-preserved provincial Roman cities in the world, its public buildings surviving to greater height than almost any other site outside Italy. The Oval Forum (a unique architectural form, probably first century CE), the colonnaded cardo and decumanus, the South Theatre (3,000 seats), and the temples of Artemis and Zeus are all substantially intact. The city was occupied continuously from Hellenistic times through the Byzantine and Islamic periods; the layered stratigraphy is visible in the site's archaeological zones. The site is accessible from Amman; a half-day visit covers the main monuments.
4. Baalbek, Bekaa Valley, Lebanon
Baalbek — ancient Heliopolis — contains the Temple of Jupiter, the largest temple of the Roman world, and the best-preserved Temple of Bacchus, whose interior carved decoration (second century CE) is among the finest surviving examples of Roman religious architecture. The Temple of Jupiter's podium consists of a foundation layer of monoliths including the Trilithon — three blocks each weighing approximately 800 tonnes, the largest dressed stones used in any ancient building. The column height of the Temple of Jupiter's original 54 Corinthian columns (six survive standing) reached 21 metres. A UNESCO World Heritage Site; accessible from Beirut despite Lebanon's political difficulties.
5. Volubilis, Morocco
Volubilis, 33 km north of Meknes, is the best-preserved Roman city in North Africa west of Libya. The site preserves a substantial area of residential and public architecture including the Capitoline temple, a basilica, an arch of Caracalla, and a dense residential quarter with in situ mosaic floors of exceptional quality — hunting scenes, mythological subjects, and portrait medallions. The city was a provincial capital of Mauretania Tingitana until the third century CE and continued under local Berber rule thereafter. A UNESCO World Heritage Site; accessible from Meknes in a half-day.
6. Caesarea Maritima, Israel
Caesarea, built by Herod the Great between 22 and 10 BCE as a major Mediterranean port, is the most archaeologically rich Roman site in Israel. Herod constructed an entirely artificial harbour using hydraulic concrete poured underwater (one of the first uses of this technique in the ancient world), a city grid on Hellenistic principles, an amphitheatre, a theatre, a palace on a sea promontory, and a temple to Augustus and Roma. The site has been excavated by a joint American-Israeli-Canadian consortium since the 1970s; ongoing excavation continues to reveal new elements. The underwater remains of the harbour are accessible for diving. A national park; accessible from Tel Aviv.
7. Sbeitla (Sufetula), Tunisia
Sbeitla in central Tunisia preserves the most complete extant Roman forum in Africa, unusually arranged with three individual temples — to Jupiter, Juno, and Minerva — rather than a single Capitoline temple. The temples face a large paved forum courtyard through a monumental arch. The city was the brief capital of the Byzantine Exarchate of Africa in 647 CE and was sacked by the Arab conqueror Abdullah ibn Saad the same year; the relative lack of post-Roman occupation has preserved its Roman character. Accessible from Kasserine; open year-round.
8. Dougga (Thugga), Tunisia
Dougga, on a hilltop in northern Tunisia, has the best-preserved small Roman town in North Africa, including a theatre (second century CE) with a 3,500-seat capacity still used for performances, a Capitol (second century CE) with three surviving columns, a Libyco-Punic mausoleum that produced the Bilingual Inscription used to partially decipher the Libyan script, and a dense residential quarter. The site's hilltop position provided natural defence and has preserved it from major disturbance. A UNESCO World Heritage Site; accessible from Teboursouk.
9. Split (Diocletian's Palace), Croatia
Diocletian's retirement palace at Split, built between 295 and 305 CE, is one of the most remarkable Roman monuments still in use: the town of Split has grown up inside the palace walls, with houses, restaurants, and shops occupying the Roman chambers, courtyards, and substructures. The palace was built for the retiring emperor on a castrum (military camp) plan covering 3.5 hectares, with four entrance gates, a peristyle, mausoleum (now the Cathedral of Saint Domnius), and a Temple of Jupiter (now a baptistery). The subterranean vaults (cellars) beneath the main floor are open and provide a complete plan of the imperial apartments above them. A UNESCO World Heritage Site; the old town is fully accessible and free.
10. Palmyra (Tadmur), Syria
Palmyra in the Syrian desert was the most important commercial city of the Roman east, enriched by its position at the junction of trans-desert caravan routes between the Mediterranean and the Parthian/Sassanid empire. The city's monuments — the Temple of Bel (first century CE), the Great Colonnade, the Theatre, the Valley of the Tombs with its funerary towers — are among the most extensive and elegant in the Roman world. ISIS occupied Palmyra in 2015–2016 and deliberately destroyed the Temple of Bel, the Temple of Baalshamin, and the Arch of Triumph, and murdered the site's head of antiquities, Khaled al-Asaad. The surviving monuments, though damaged, remain substantial. Security conditions permitting, Palmyra is accessible from Homs or Damascus.
