The Most Remarkable Ancient Archaeological Sites in Europe
17 places in 5 countries · updated 14 October 2026
In short: By our ranking, the most remarkable ancient archaeological sites in Europe are Colosseum (Italy), Roman Forum (Italy) and Castel Sant'Angelo (Italy). The list covers 17 ancient archaeological sites in 5 countries. Italy has the most, with 9. Last updated 14 October 2026.
Ancient Europe left its mark in stone more durably than almost anywhere else. Neolithic farmers built temples and villages from the islands of Malta to the Orkneys, the Minoans and the Greeks raised palaces and temples around the Aegean, and Rome spread roads, walls and monuments across the continent. Because many later cities grew directly on top of these foundations, the ancient world is not only excavated here but still lived among.
Rome itself is the densest concentration. The Colosseum, inaugurated in AD 80, could hold tens of thousands of spectators, the Roman Forum was the political and religious heart of the city, and Trajan's Column wraps a continuous spiral relief of the Dacian Wars around its shaft. Castel Sant'Angelo began as the mausoleum of Hadrian before becoming a papal fortress. To the south, Pompeii was buried by Vesuvius in AD 79 and preserved as a snapshot of Roman daily life, and Paestum keeps three Doric temples built by Greek colonists.
Greece holds the roots of the classical world: the Parthenon on the Acropolis of Athens, built in the fifth century BC, and Knossos on Crete, the great Bronze Age palace of the Minoans. In Split, Diocletian's Palace became the core of a living town. The oldest sites take the story back further still: Ġgantija on Gozo is among the oldest free-standing stone structures in the world, Skara Brae in Orkney preserves stone houses with built-in furniture from the Neolithic, and Hadrian's Wall crosses northern England as the frontier of Roman Britain.

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 Castel Sant'Angelo
Italy · 1.4 km from Rome41.903° N 12.466° E
Image by rainhard2 from Pixabay Hadrian started building his own tomb in 123 CE and didn't live to see it finished — it was completed in 139 under his successor Antoninus Pius, a cylindrical drum of a monument meant to hold the ashes of an emperor and his family for eternity. Eternity lasted about three centuries as a mausoleum.
Did you know? The current bronze angel by Peter Anton von Verschaffelt replaced a 1536 marble Saint Michael by Raffaello da Montelupo in 1753.
04 Trajan's Column
Colonna Traiana
Italy · 0.3 km from Rome41.896° N 12.484° E
Raffaele pagani · CC BY-SA 4.0 Trajan's Column is a 30-metre marble shaft, 35 m with its pedestal, that has stood in Trajan's Forum just north of the Roman Forum since it was dedicated on 12 May 113. It celebrates Emperor Trajan's two wars against the Dacians in 101-102 and 105-106, and it was most likely designed under the architect Apollodorus of Damascus.
Did you know? The lettering of the dedication on the base became the classic model of Roman square capitals, and Carol Twombly based her 1989 Trajan typeface on it.
05 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.
06 Knossos
Κνωσός
Greece · 4.2 km from Heraklion35.298° N 25.163° E
Image by davestem from Pixabay Knossos, on Kephala hill 5 km south of the centre of Heraklion, was the greatest centre of Minoan Crete and is often described as Europe's oldest city. People settled on the hill around 7000 BC, and by about 1900 BC they had built the first palace: a multi-storey complex around a central court, covering roughly 20,000 m², with storerooms, workshops, shrines and halls of state.
Did you know? The Throne Room, built in the 15th century BC, is considered the oldest throne room in Europe, and its alabaster seat the oldest stone throne on the continent.
07 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.
08 Pompeii
Pompei
Italy · 23.2 km from Naples40.751° N 14.490° E
Glen Scarborough from The Central Coast, Australia · CC BY 2.0 Pompeii is the most complete picture we have of an ordinary Roman town, and it owes that to the catastrophe that ended it. In AD 79 Vesuvius, about 8 km away, erupted for two days. First came some eighteen hours of falling pumice, which let many of the inhabitants flee; then surges of superheated gas and ash swept through the streets and killed those who had stayed.
Did you know? After Sulla captured the town in 89 BC it became a colony of his veterans, renamed Colonia Cornelia Veneria Pompeianorum.
09 Hadrian's Wall
United Kingdom55.024° N 2.292° W
- UNESCO World Heritage
Image by 18623647 from Pixabay Hadrian's Wall crosses the whole width of northern England, from Wallsend on the River Tyne in the east to Bowness-on-Solway on the Solway Firth in the west — 80 Roman miles, or about 117 km. The Emperor Hadrian ordered it built in AD 122 to mark the northern edge of the province of Britannia.
Did you know? Around 15,000 soldiers from three legions, helped by men of the Roman fleet, built most of the wall in about six years.
10 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.
11 Skara Brae
United Kingdom · 24.3 km from Kirkwall59.049° N 3.342° W
- UNESCO World Heritage
Giorgio Galeotti · CC BY-SA 4.0 Skara Brae is a Neolithic village on the Bay of Skaill, on the west coast of Orkney's Mainland, and the most complete settlement of its age in Europe. People lived here from about 3180 BC for some six centuries. The village lay hidden under a grassy mound until the winter of 1850, when a great storm stripped the dunes and exposed the outlines of roofless stone houses.
Did you know? V. Gordon Childe first believed the village dated from around 500 BC; radiocarbon dating in 1972–73 showed it was some 2,500 years older.
12 Paestum
Italy · 34.9 km from Salerno40.423° N 15.006° E
- UNESCO World Heritage
Image by SCAPIN from Pixabay Paestum, on the plain south of Salerno, has three Greek temples in the Doric order that are among the best preserved anywhere, standing in open fields inside an almost complete ring of ancient walls. Settlers from Sybaris founded the city around 600 BCE as Poseidonia; the Lucanians took it at the end of the 5th century BCE, and Rome made it a Latin colony called Paestum in 273 BCE.
Did you know? Only about 25 of the city's roughly 120 hectares have been excavated; the rest lies under private land, still unexplored.
13 Ġgantija
Malta · 27.5 km from Valletta36.047° N 14.269° E
- UNESCO World Heritage
Vitold Muratov · CC BY-SA 4.0 Ġgantija stands on the edge of the Xagħra plateau on Gozo, the second island of the Maltese archipelago, and it is the oldest of the megalithic temples that make up the Maltese World Heritage listing. Its two temples were raised around 3600 BC, which puts them centuries ahead of the Egyptian pyramids.
Did you know? Ġgantija is regarded as the second-oldest surviving human-built religious structure in the world, younger only than Göbekli Tepe in Turkey.
14 Pantheon, Rome
Pantheon
Italy · 0.4 km from Rome41.899° N 12.477° E
Image by falcon505 from Pixabay The Pantheon is the best-preserved great building of ancient Rome, and its interior is one of the most perfect spaces ever built. The temple first raised by Marcus Agrippa under Augustus burned down; the building that stands today was reconstructed under the emperor Hadrian and completed around AD 126.
Did you know? Two small bell towers added in the 17th century were mocked by Romans as ass's ears and finally taken down in 1883.
15 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.
16 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.
17 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.
