The 10 Most Awe-Inspiring Ancient Structures in Asia

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.

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.

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.

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.

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.

The Longmen Grottoes hold tens of thousands of Buddhist statues and carvings, from finger-sized figures to a 17-metre Buddha, cut into limestone cliffs along the Yi River over roughly 400 years starting in the 5th century.

It's one of China's three great ancient sculptural sites, and the riverside setting makes it easy to view carvings from a boat as well as on foot.

Many statues were damaged or looted over the centuries, visible alongside what survives.

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.

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.
