The Most Beautiful Ancient Ruins in the World
8 places in 3 countries · updated 14 October 2026
In short: By our ranking, the most beautiful ancient ruins in the world are Colosseum (Italy), Roman Forum (Italy) and Diocletian's Palace (Croatia). The list covers 8 ancient ruins in 3 countries. Italy has the most, with 4. Last updated 14 October 2026.
Ancient ruins carry the clearest evidence of how the Mediterranean world built: the column, the arch and the vault, the forum and the amphitheatre, all invented or perfected by Greeks and Romans and copied ever since. What survives is shaped by marble and travertine that outlasted every later use, and by the reuse itself — temples turned into churches, a palace turned into a town. Standing among them, the proportions that later architecture borrowed can be seen in the original.
The Colosseum in Rome, inaugurated under Emperor Titus in 80 AD, is the largest amphitheatre ever built, its travertine arcades still standing on three levels. Below it lies the Roman Forum, the centre of public life in the city, where temples, basilicas and triumphal arches crowd a single valley between the Palatine and Capitoline hills.
The others show what happened to ancient buildings afterwards. The Parthenon on the Acropolis of Athens, built in the fifth century BC for Athena, became a church, a mosque and a powder store before its ruin. Diocletian's Palace in Split, the retirement residence of a Roman emperor, was later filled with the houses of a medieval town. The Temple of Aphaia on Aegina is one of the best preserved early Doric temples, standing among pines on a hilltop above the Saronic Gulf.

01 Colosseum
Colosseo
Italy · 1.2 km from Rome41.890° N 12.492° E
Image by MARTINOPHUC from Pixabay The eighty-foot drop beneath the Colosseum's sand floor is where the real machinery of the show lived.
Did you know? It held an estimated 50,000 to 80,000 spectators, making it the largest amphitheatre ever built in the ancient world.
02 Roman Forum
Foro Romano
Italy · 0.7 km from Rome41.892° N 12.485° E
Image by jensjunge from Pixabay The Roman Forum fills a small valley between the Palatine and Capitoline hills that was once a marsh. Drained in the 7th century BC by the first stretch of the Cloaca Maxima, the great sewer that emptied into the Tiber, it became the place where Rome did everything in public: voted, traded, tried criminals, heard speeches, worshipped and celebrated its triumphs.
Did you know? Long before it was a public square, part of the Forum served as an Iron Age cemetery in the 10th century BC, with cremation urns buried in large clay jars.
03 Diocletian's Palace
Dioklecijanova palača
Croatia · 2.9 km from Split43.508° N 16.438° E
- UNESCO World Heritage
Image by neufal54 from Pixabay Diocletian, the emperor who divided power among four rulers and then did something rare for a Roman emperor — abdicated, in 305 — chose a peninsula on the Dalmatian coast for his retirement, a few kilometres from Salona, the provincial capital.
Did you know? In the 7th century a small church of St Martin was built above the Golden Gate.
04 Parthenon
Παρθενώνας
Greece · 1.6 km from Athens37.972° N 23.727° E
- UNESCO World Heritage
Image by nonbirinonko from Pixabay The Parthenon looks perfectly straight only because almost nothing about it actually is.
Did you know? On 26 September 1687 a Venetian mortar round hit gunpowder stored inside by the Ottoman garrison, and the blast killed about 300 people.
05 Trajan's Market
Mercati di Traiano
Italy · 0.5 km from Rome41.896° N 12.486° E
NikonZ7II · CC BY-SA 4.0 Trajan's Market is a curved cliff of Roman brick set into the side of the Quirinal Hill, above the ruins of Trajan's Forum and across Via dei Fori Imperiali from the Vittoriano. It was probably built between about AD 100 and 110, most likely to designs by Apollodorus of Damascus, Trajan's architect for the forum and for his campaigns, and inaugurated in 113.
06 Domus Aurea
Italy · 1.4 km from Rome41.891° N 12.495° E
Unknown author Unknown author · Public domain Buried under the Oppian Hill, a stone's throw from the Colosseum, lie the vaulted halls of the most extravagant palace ancient Rome ever saw.
Did you know? An artificial lake in Nero's grounds occupied the valley where the Colosseum was later built.
07 Temple of Apollo Epicurius in Bassae
Ναός Επικούριου Απόλλωνα
Greece37.430° N 21.900° E
- UNESCO World Heritage
Jean Housen · CC BY-SA 4.0 On a bare limestone shoulder of Mount Kotilion, more than 1,100 metres up in the wild hills where ancient Arcadia met Messenia, stands one of the best-preserved temples of classical Greece. Its name, Bassai, means roughly a little vale among the rocks, and the setting is exactly that: grey stone, oak scrub and a long view over ridges towards the sea.
Did you know? Bassae became the first Greek site on the UNESCO World Heritage List in 1986.
08 Temple of Aphaia, Aegina
Ναός της Αφαίας
Greece · 26.2 km from Piraeus37.754° N 23.533° E
Image by aled7 from Pixabay On a hilltop in the east of Aegina, an island in the Saronic Gulf, the Doric columns of the Temple of Aphaia still stand around their cella, though the roof is long gone. Built around 500 BC, the temple is remarkable for an unusual plan and above all for its pediment sculptures, which capture the moment when Greek art was turning from the Archaic to the Early Classical style.
Did you know? Proposed construction dates for the surviving temple range from 510 to 470 BC, with around 500 BC most widely favoured.
How this list is ranked
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 — 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.
