Great Wall of China

The Great Wall of China is not one wall but a mosaic of fortifications built, rebuilt and abandoned over some two millennia along China's northern frontier. Its earliest sections date to the 7th–4th century BCE, in the Spring and Autumn and Warring States periods; in 221 BCE Qin Shi Huang connected existing walls into a single system, and later dynasties — most famously the Ming (1368–1644) — extended and faced the line with brick and stone. The most authoritative modern figure comes from a state survey conducted since 2007: the State Administration of Cultural Heritage announced in June 2012 that all sections of the wall total 21,196.18 kilometres; the Ming wall alone is about 8,850 km, per Britannica, running from Mount Hu near Dandong to Jiayu Pass in Gansu. UNESCO inscribed the Great Wall as a World Heritage site in 1987 and calls it an absolute masterpiece of military architecture; protection today rests on the 2006 Regulations on the Protection of the Great Wall, a 2019 conservation plan, the national cultural park programme, and provincial laws such as Shanxi's 2026 regulations. The popular claim that the wall is visible from space — or from the Moon — is a myth: NASA, National Geographic and Britannica all state it is not visible to the naked eye from the Moon and is difficult or impossible to see from Earth orbit without high-powered lenses.

Japan

Japan is an island country off the eastern coast of Asia whose crescent-shaped archipelago stretches some 2,400 kilometres from Hokkaido to the Ryukyus; an official recount in 2023 put the number of its islands at 14,125. Its 123.8 million people — 29.3 per cent of them aged 65 or over, and falling in number since 2008 — live mostly in the great metropolitan belts of the Pacific coast, above all Greater Tokyo. Under Emperor Naruhito, the 126th of a line traditionally traced to 660 BCE, Japan is a constitutional monarchy with a parliamentary Diet; its 1947 constitution renounces war. Industrialisation after the 1868 Meiji Restoration and reconstruction after 1945 made Japan one of the world's largest economies — a position now measured in the yen's terms, a government debt above 200 per cent of GDP, and a technological and cultural reach that includes 27 World Heritage properties and UNESCO-listed cuisine and theatre.

Kuwait

Kuwait is a small constitutional monarchy on the Persian Gulf, bordered by Iraq and Saudi Arabia. It grew from an 18th-century Bedouin trading post into one of the world's most urbanized countries, with an economy anchored in oil and overseas investment. The country gained independence from Britain in 1961, endured invasion and occupation by Iraq in 1990–1991, and today ranks among the richest countries per person.

Machu Picchu

Machu Picchu is the most famous and best-preserved city of the Inka Empire: roughly 200 buildings, temples, terraces and fountains fitted together without mortar on a granite saddle 2,430 metres above the sea, between the peak of Machu Picchu and Huayna Picchu. Built around AD 1450 as a royal estate attributed to the Inka Pachakuti, it was abandoned in the sixteenth century and hidden by cloud forest until Hiram Bingham reached it on 24 July 1911. Since then it has become a UNESCO World Heritage site (1983), one of the New Seven Wonders of the World (2007), the subject of a century-long dispute over the artifacts Bingham removed, and a laboratory for engineers and archaeologists studying Inka drainage, masonry and land use. This fact file gathers the evidence from UNESCO's World Heritage records, Peru's Ministry of Culture and the National Archaeological Park of Machu Picchu, Yale University, National Geographic, Britannica, Hiram Bingham's own 'Inca Land' and 1913 expedition report, and peer-reviewed research in Radiocarbon, Scientific Reports, NHESS and the Journal of Irrigation and Drainage Engineering.

Rome

Rome is the capital of Italy and of the Lazio region, a city on the Tiber about 24 km (15 miles) inland from the Tyrrhenian Sea, with a municipal territory of 1,285 km2. Legend places its founding by Romulus and Remus in 753 BC — the anniversary is still kept on 21 April — and it was successively the centre of the Roman Republic (from 509 BC), of the Roman Empire (from 27 BC) and, from the 4th century, of the Christian world. The popes rebuilt it in the Renaissance and Baroque eras, and in 1871 it became the capital of a united Italy, with Vatican City — the world's smallest independent state, created by the 1929 Lateran Treaty — enclosed inside it. Its historic centre, ringed by the Aurelian Walls, entered the UNESCO World Heritage List in 1980 and was extended in 1990. The monuments of antiquity survive in extraordinary density — the Colosseum (dedicated AD 80), the Pantheon (rebuilt 118-125), Trajan's Column (106-113), Hadrian's mausoleum (135-139) and the Baths of Caracalla (206-216) — beside St Peter's Basilica, dedicated in 1626, and the Trevi Fountain, completed in 1762. ISTAT put the city's population at 2,745,062 on 1 January 2026.

Saudi Arabia

Saudi Arabia is an absolute monarchy occupying most of the Arabian Peninsula. Unified in 1932 by Abdulaziz Al Saud, it is the custodian of Islam's two holiest cities, Mecca and Medina, and one of the world's largest oil producers. Its economy and society have been reshaped in recent years by the reform program of Crown Prince Mohammed bin Salman, while its heritage — from the Al-Ahsa Oasis to the annual Hajj — remains central to its identity.

Stonehenge

Stonehenge is a prehistoric stone circle, cemetery and archaeological site on Salisbury Plain in Wiltshire, England, built in several stages from about 3000 BC, with the central stone settings raised about 2500 BC. Its large sarsens came from the Marlborough Downs about 25 km north, its smaller bluestones from the Preseli Hills of south-west Wales, and the whole layout is aligned on the solstices. This fact base assembles the evidence of English Heritage, UNESCO, the British Museum, Historic England research reports and peer-reviewed archaeology — including the open disputes over bluestone transport and the Altar Stone's origin — with verbatim quotes from each source.

Venice

Venice is the lagoon city of the northern Adriatic: 118 islands joined by canals and bridges inside a crescent-shaped lagoon, once the capital of a maritime republic that dominated the eastern Mediterranean, and today a World Heritage site fighting to stay habitable. This fact file gathers the evidence behind the story: UNESCO’s 1987 inscription and the advisory missions that twice recommended placing the site on the Danger List; the tide records — 194 cm on 4 November 1966 and 187 cm on 12 November 2019; the MOSE system of 78 mobile gates, operational since October 2020 and now raised about 20 times a year; the shifting statistics of residents, visitors and cruise ships; and the scientific record of a lagoon whose salt marshes have shrunk by half since 1927.
