7 places ยท updated 14 October 2026
In short: By our ranking, the most beautiful ruins in Italy are Colosseum, Roman Forum and Trajan's Market. The list covers 7 ruins. Last updated 14 October 2026.
Italy's ruins are layered like no other country's: Greek colonies in the south, the capital of the Roman Empire at the centre, and medieval abbeys left open to the sky. Stone was reused, earthquakes struck and towns grew over the old ones, yet so much survived that the ruins themselves shaped how Europe learned to see the past.
The Colosseum, inaugurated in AD 80, is the largest amphitheatre ever built and still dominates the centre of Rome. Beside it, the Roman Forum gathers the temples, basilicas and triumphal arches of the city's civic heart into one sunken valley. The Temple of Concordia in Agrigento, built by Greek colonists in the 5th century BC, is one of the best-preserved Doric temples anywhere, saved by its conversion into a church. The Abbey of San Galgano in Tuscany is a Cistercian church whose roof has long gone, leaving Gothic arches open to the sky and grass for a floor.

Colosseo
Italy ยท 1.2 km from Rome41.890ยฐ N 12.492ยฐ E

Its life after the games ended in the early 5th century was almost as eventful as its life as an arena. Medieval Romans turned it into housing and workshops, then a fortress for rival noble families; later centuries saw it stripped for building material, its travertine blocks hauled off to build palaces and even St Peter's Basilica. A major earthquake in 1349 collapsed the entire outer wall on the south side, where the ground is softer โ which is why, looking at it today, one side reads as a complete ring and the other as a ragged cross-section, exposing the inner corridors like a cutaway diagram. Only about a third of the original structure survives.
Did you know? The pockmarks covering the walls were left by medieval scavengers who hacked out the iron clamps that once held the stone blocks together.
Foro Romano
Italy ยท 0.7 km from Rome41.892ยฐ N 12.485ยฐ E

After the empire fell the Forum was buried under silt and rubble and used as grazing land, the Campo Vaccino. Renaissance popes quarried it hard, above all in the 1540s when Paul III took its marble for the new St Peter's. Clearance began in 1803 at the Arch of Septimius Severus, and systematic state excavation from 1898; digging continues today. The travertine paving laid under Augustus is still visible, and the line of the Via Sacra, the road of the triumphal processions, still runs through the ruins between the two arches.
Did you know? Marble paving laid under Sulla in the 80s BC survived largely intact for over a thousand years, until the Norman sack of Rome in 1084.
Mercati di Traiano
Italy ยท 0.5 km from Rome41.896ยฐ N 12.486ยฐ E

Since 2007 the complex has housed the Museum of the Imperial Fora, which gathers finds from all of ancient Rome's imperial forums. It is a quieter and more understandable visit than the main Forum, and a good place to understand how Roman concrete architecture actually worked.
Scavi archeologici di Ercolano
Italy ยท 9.7 km from Naples40.806ยฐ N 14.348ยฐ E

The strongest moment is at the old shoreline. In the vaulted boathouses facing what was then the beach, excavations since 1980 have found the remains of about 340 people who had fled there and waited for boats that never came; casts of the skeletons lie where they were found, and one of them, an officer with a dagger and belt, may have been part of a rescue mission. Since 2001 the Herculaneum Conservation Project has turned the site round after years of neglect. The Villa of the Papyri, north-west of the town, is still mostly underground.
Tempio della Concordia
Italy37.290ยฐ N 13.592ยฐ E

Walk toward it along the ancient ridge of the Valley, which carries a whole line of Greek temples, and watch it grow in front of you; seen from a distance, with olive and almond country around it, it still reads as the landmark it was meant to be. The Valley of the Temples is a UNESCO World Heritage Site.
Did you know? The temple stands about 8.9 metres high on a four-stepped platform measuring roughly 39.4 by 16.9 metres.
Italy ยท 1.4 km from Rome41.891ยฐ N 12.495ยฐ E

Nero's successors hurried to erase his memory. Within a few decades the palace was stripped, filled with earth and built over: the Flavian emperors drained the lake for the Colosseum, and Trajan raised his baths on top of the Oppian wing. Paradoxically, the burial preserved the paintings. Around the end of the 15th century they were rediscovered, and artists such as Pinturicchio, Ghirlandaio and Raphael were lowered into the dark chambers they took for caves, or grotte, to copy the fanciful painted ornament. From those 'grottoes' comes the word grotesque, and the style fed straight into Raphael's Vatican Loggias and, centuries later, into Neoclassical decoration.
Did you know? An artificial lake in Nero's grounds occupied the valley where the Colosseum was later built.
Abbazia di San Galgano
Italy ยท 24.4 km from Siena43.149ยฐ N 11.155ยฐ E

A short walk uphill stands the round Hermitage of Montesiepi, built on the site of Galgano's own retreat, where a sword is set into the rock at the chapel's centre. Legend holds that Galgano drove it there himself when he renounced worldly life to become a hermit โ a story that, unusually, has a sliver of physical backing: metallurgical analysis has dated the sword itself to the 12th century, the period in which Galgano actually lived.
Did you know? From 1257 monks of the abbey repeatedly held the office of camerlengo of the Biccherna, in effect running the treasury of the Republic of Siena.
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented โ the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
