Hagia Sophia
Istanbul, Turkey · 537 CE
Built as a cathedral under Emperor Justinian I, converted to a mosque after the 1453 Ottoman conquest, secularised into a museum in 1934, then reconverted to a working mosque again in 2020 — few buildings anywhere have changed religious function this many times while remaining continuously in use. Its unsupported central dome was the largest in the world for nearly a thousand years. Recorded specifics: country Turkey, built 537, visitors/yr 3.7 M. Panel highlighted unsupported central dome held the record for the largest in the world for close to a millennium, interior mosaics and calligraphy from both its Christian and Islamic eras remain visible side by side and continuously occupied and maintained for nearly 1,500 years, an unusually long unbroken record. The reservation on record is its 2020 reconversion to an active mosque restricts viewing of some Byzantine mosaics during prayer times.

Ranked alongside it
Rank 01Editor’s pickGreat Pyramid of Giza
Giza, Egypt · c. 2560 BCE
The only surviving Ancient Wonder of the World, built as a tomb for the pharaoh Khufu from roughly 2.3 million limestone blocks with a precision that still defies a fully agreed explanation of the construction method. It held the title of tallest human-made structure on Earth for almost 3,800 years, longer than any building before or since.

Rank 02Editor’s pickGreat Wall of China
Northern China · primarily Ming dynasty, 1368–1644
Not one continuous wall but a patchwork of fortifications built and rebuilt by successive dynasties over two thousand years, stretching a combined length estimated at over 21,000 kilometres including all branches and spurs. Most of what tourists actually visit today is Ming-era construction, since earlier sections have largely eroded back into the landscape.

Rank 03Editor’s pickMachu Picchu
Cusco Region, Peru · c. 1450 CE
Built by the Inca as a royal estate roughly 2,430 metres up in the Andes and abandoned within a century, it stayed unknown to the outside world until Hiram Bingham’s 1911 expedition brought it to global attention. Dry-stone construction fits blocks so precisely that no mortar was needed and few joints admit even a knife blade.

Rank 04Editor’s pickPetra
Ma’an Governorate, Jordan · c. 300 BCE
The Nabataeans carved an entire city into rose-coloured sandstone cliffs, engineering a water-management system sophisticated enough to support a desert trading capital of an estimated 20,000 people. Most visitors see only the Treasury facade near the entrance; the full site extends for several kilometres beyond it.

Rank 05Colosseum
Rome, Italy · 80 CE
The largest amphitheatre ever built in the Roman world, capable of seating an estimated 50,000 to 80,000 spectators for gladiatorial contests and staged animal hunts, with an underground hypogeum of trapdoors and lift mechanisms that could raise scenery and combatants directly into the arena floor.

Rank 06Taj Mahal
Agra, India · completed 1653
Emperor Shah Jahan commissioned it as a mausoleum for his wife Mumtaz Mahal, who died in childbirth, and it took an estimated 20,000 workers over two decades to complete in white Makrana marble that shifts colour with the light through the day. The emperor was later imprisoned by his own son within sight of it.

Rank 07Editor’s pickAngkor Wat
Siem Reap, Cambodia · early 12th century
Built originally as a Hindu temple to Vishnu before gradually becoming Buddhist, Angkor Wat is the largest religious monument on Earth by land area and the centrepiece of a much larger metropolitan complex that may once have supported close to a million people, one of the largest pre-industrial urban settlements ever documented.

Rank 08Editor’s pickChichen Itza
Yucatán, Mexico · c. 600–900 CE
The Maya city’s central pyramid, El Castillo, is engineered so precisely that during the spring and autumn equinoxes, sunlight and shadow form the illusion of a serpent slithering down its staircase — a deliberate astronomical alignment rather than a coincidence.
