The 27 Most Awe-Inspiring Ancient Structures in The World

Machu Picchu is the 15th-century Inca citadel set high in the Andes at 2,430 metres, concealed from the Spanish conquistadors and unknown to the outside world until Hiram Bingham III's expedition in 1911.

Its stone temples, terraced agricultural land, and mountain setting create one of the world's most atmospheric ancient sites.

Stretching over 21,000 kilometres across northern China, the Great Wall is one of the greatest architectural achievements in human history.

The restored sections near Beijing, such as Mutianyu and Jinshanling, wind dramatically across steep mountain ridges and can be walked in a few hours.

Further out, unrestored stretches crumble into the hillsides largely unvisited.

The Great Pyramid of Giza is the oldest of the Seven Wonders of the Ancient World and the only one still standing, built as a tomb for Pharaoh Khufu around 2560 BC.

The three pyramids on the Giza plateau, together with the Great Sphinx, are the most recognisable ancient monuments on earth.

Petra is an ancient Nabataean city carved directly into rose-red sandstone cliffs in southern Jordan.

Known as the Rose City, its most iconic monument is Al-Khazneh, or the Treasury, a 40-metre-high temple facade with Hellenistic columns that appears dramatically at the end of the narrow Siq canyon.

Mont Saint-Michel is a tidal island commune in Normandy topped by a medieval Benedictine abbey that soars 80 metres above the surrounding tidal flats.

When the sea retreats, the island is connected to the mainland by a causeway; when the tide comes in at one of the fastest rates in Europe, the island becomes a castle rising from the sea.

Buried for over two thousand years to guard the tomb of China's first emperor, the Terracotta Army was discovered by farmers digging a well in 1974 and remains one of the most significant archaeological finds of the twentieth century.

More than 8,000 life-sized soldiers, each with individually sculpted facial features, stand in battle formation inside three vast excavation pits, alongside horses, chariots, and officers.

Chichen Itza was one of the great cities of the Maya world, and its restored centrepiece, the stepped pyramid of El Castillo, is the image of pre-Columbian Mexico.

The temple is a stone calendar: at the equinoxes the afternoon sun casts a serpent of shadow down its northern staircase.

Beyond it sprawl the Great Ball Court, the Temple of the Warriors and a thousand columns.

The Colosseum is the largest amphitheatre ever built and an enduring symbol of the power and ingenuity of ancient Rome.

Completed in 80 AD, it could hold up to 80,000 spectators who came to watch gladiatorial contests, animal hunts, and public spectacles that defined Roman entertainment culture.

Hegra was the second city of the ancient Nabataean kingdom after Petra, and its more than 100 monumental tombs, carved into sandstone outcrops across a desert plain, survive in far better condition than their Jordanian counterpart.

Saudi Arabia's first UNESCO World Heritage site opened to tourism only in 2019, and the tombs still show sharp carved detail after two thousand years in the desert.

Roughly 900 moai, the monumental stone figures carved by the Rapa Nui between the 13th and 16th centuries, are scattered across this small volcanic island 3,700km from mainland Chile.

The best-known cluster, fifteen restored moai at Ahu Tongariki, catches the sunrise directly behind it.

Elsewhere, the Rano Raraku quarry has dozens of unfinished statues still half-buried in the hillside where their carvers left them.

Towering limestone pyramids rise straight out of dense rainforest canopy at this former Maya city-state, once home to an estimated 90,000 people at its peak around 800 CE.

Howler monkeys and toucans fill the surrounding jungle, and climbing Temple IV at dawn puts visitors above the canopy to watch other temple roofs emerge from mist.

Far less restored than Mexico's Chichen Itza, Tikal feels genuinely like a lost city rather than a manicured park.

An ancient rock fortress rises 200 meters from the Sri Lankan jungle, its summit holding the ruins of a 5th-century royal palace.

Frescoed cave paintings, a mirror wall polished by centuries of visitors' inscriptions, and a giant carved lion's paw gateway mark the final climb to one of Asia's most dramatic archaeological sites.

Over 2,000 Buddhist temples and pagodas dating to the 11th–13th centuries scatter across a dusty plain beside the Irrawaddy River.

Hot-air balloons drift over the gilded spires at sunrise, and even at ground level the density of ancient structures is unmatched anywhere in Southeast Asia.

Ephesus is one of the best-preserved ancient cities in the Mediterranean, its marble streets lined with the two-storey facade of the Library of Celsus, a restored amphitheatre that once seated 25,000, and the remains of temples, baths, and terraced houses.

Founded as a Greek colony and later a major Roman port, it gives a more complete sense of ancient urban life than almost any other ruin still standing today.

Teotihuacan was one of the largest cities in the ancient world, and its two great pyramids — the Sun and the Moon — still dominate the Mexican plateau just outside the capital.

The Avenue of the Dead runs more than two kilometres between them, past palace complexes decorated with faded murals.

Both main pyramids can be climbed, and the view from the top of the Pyramid of the Sun takes in the whole site and the mountains beyond.

Delphi was the ancient world's most important oracle, where pilgrims travelled from across the Mediterranean to consult the priestess of Apollo.

The sanctuary's ruins climb a steep slope of Mount Parnassus overlooking a valley of olive groves that stretches to the Gulf of Corinth, and the on-site museum holds the bronze Charioteer, one of the finest surviving Greek statues.

The Acropolis of Athens is a flat-topped hill rising 150 metres above the city, crowned by the Parthenon — the greatest surviving monument of ancient Greek civilisation.

Built under the direction of Pericles between 447 and 432 BC, the marble temple dedicated to the goddess Athena has stood as a symbol of democracy and Western culture for 2,500 years.

Four colossal 20-meter statues of Ramesses II guard the entrance to this rock-cut temple complex, built to intimidate travelers approaching from the south and, remarkably, entirely relocated in the 1960s to save it from the rising waters of Lake Nasser after the Aswan Dam was built.

Twice a year, sunlight penetrates 60 meters into the temple to illuminate statues in the inner sanctuary — a feat of ancient astronomical engineering.

Ayutthaya was the capital of Siam for four centuries and one of the largest cities in the world before Burmese armies destroyed it in 1767, leaving rows of brick temple spires and headless Buddha statues across the old city island.

Its best-known image is a stone Buddha head cradled in the roots of a banyan tree at Wat Mahathat, but the wider site holds dozens of temple ruins connected by quiet canals and cycling paths.

Tulum is the only major Maya city built directly on the coast, its stone temples and watchtowers standing on a low cliff above a beach of white sand and turquoise water.

The site is small compared to Chichén Itzá, but the setting — walled ruins on one side, Caribbean Sea on the other — is unmatched.

Visitors can walk the perimeter path in under an hour, then head down the wooden stairs to swim below the cliffs.

This Neolithic passage tomb in the Boyne Valley predates Stonehenge and the Egyptian pyramids by centuries, its huge circular mound ringed with carved kerbstones and a roof-box aligned to flood the inner chamber with sunlight at the winter solstice.

Guided tours take you inside the narrow passage to the burial chamber, and a simulated solstice light show runs year-round.

The precision of 5,000-year-old engineering is the real draw.

Diriyah was the original capital of the first Saudi state, and the mudbrick palaces and towers of its At-Turaif district, restored and UNESCO-listed, sit above the green Wadi Hanifa valley on the edge of modern Riyadh.

Najdi architecture — thick clay walls, small windows, geometric details — survives across the old quarter, now paired with new museums, cafes, and walking paths along the wadi.

This fortified clay ksar of tightly clustered earthen buildings has stood on a Saharan trade route for centuries and become one of cinema's favorite backdrops, doubling for ancient settings in Gladiator, Game of Thrones and Lawrence of Arabia.

A handful of families still live within its walls.

Climbing to the top for views over the Ounila Valley shows off both the settlement's defensive logic and its striking desert-earth architecture.

Dedicated to the goddess Isis, this graceful temple was dismantled stone by stone and rebuilt on higher ground at Agilkia Island to save it from flooding after the Aswan High Dam was built, in a UNESCO rescue project that ran alongside Abu Simbel's.

Reached by a short boat ride across Lake Nasser's reservoir, its columned courtyards and hieroglyph-covered walls are less crowded than Luxor's temples and set in a genuinely scenic island location.

Stonehenge is a prehistoric monument on Salisbury Plain in Wiltshire, built in several phases between 3000 and 1500 BC by Neolithic and Bronze Age peoples whose precise intentions remain a mystery.

The arrangement of massive sarsen stones and smaller bluestones transported from Wales creates a monument of enduring wonder.

The best-preserved Roman ruins in Morocco sit in open farmland near Meknes, their mosaic floors — remarkably intact after nearly 2,000 years — depicting mythological scenes across the remains of villas, a basilica and a triumphal arch.

Storks nest on top of the surviving columns, and the fertile plain surrounding the site explains why Rome valued this outpost enough to build so substantially here.

Predating the Inca by centuries, Tiwanaku was the ceremonial center of a civilization that shaped much of Andean religious and architectural tradition, including monumental gateways, sunken temples and precisely cut stonework whose engineering isn't fully understood.

Much of the site remains unexcavated, and what's been uncovered — including the carved Gateway of the Sun — shows precision that later influenced Inca sites like Machu Picchu.
