Landmark rounds are a staple of any quiz night, and the questions tend to come down to the same details: who built it, when, where and why it matters. UNESCO’s World Heritage Centre publishes official descriptions and inscription dates for every site on the World Heritage List, making it one of the most reliable places to check. This guide pulls together eight famous landmarks and the facts UNESCO records about them.
How the World Heritage List works
UNESCO explains that the World Heritage idea is embodied in an international treaty, the Convention concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972. The aim is to identify, protect and preserve cultural and natural heritage considered to be of outstanding value to humanity. UNESCO describes the concept as exceptional because of its universal application: sites belong to all the peoples of the world, irrespective of the territory on which they are located.
At the time of writing in October 2026, the World Heritage List on UNESCO’s website shows 1,273 properties: 991 cultural, 240 natural and 42 mixed. These totals change as new sites are added, so a quiz answer should always specify a date.
The Pyramids of Giza and Memphis
UNESCO lists the site as “Memphis and its Necropolis, the Pyramid Fields from Giza to Dahshur”, inscribed in 1979. It describes Memphis as the capital of the Old Kingdom of Egypt, with extraordinary funerary monuments including rock tombs, ornate mastabas, temples and pyramids. UNESCO adds that in ancient times the site was considered one of the Seven Wonders of the World.
Machu Picchu, Peru
The Historic Sanctuary of Machu Picchu was inscribed in 1983. UNESCO says it stands 2,430 metres above sea level in the middle of a tropical mountain forest and was probably the most amazing urban creation of the Inca Empire at its height. Its giant walls, terraces and ramps seem as if they have been cut naturally from the continuous rock escarpments on the eastern slopes of the Andes.
The Taj Mahal, India
Also inscribed in 1983, the Taj Mahal stands on the right bank of the Yamuna River in the Agra District of Uttar Pradesh. UNESCO notes that Mughal Emperor Shah Jahan built it in memory of his wife Mumtaz Mahal, with construction starting in 1632 and completed in 1648. The mosque, guest house and main gateway were added subsequently, finishing in 1653. UNESCO names Ustad-Ahmad Lahori as the main architect.
Stonehenge, Avebury and Associated Sites, England
Inscribed in 1986, this World Heritage property in southern Britain is described by UNESCO as internationally important for its complexes of prehistoric monuments. UNESCO states that Stonehenge is the most architecturally sophisticated prehistoric stone circle in the world, while Avebury is the largest. The monuments demonstrate Neolithic and Bronze Age ceremonial and mortuary practices resulting from around 2,000 years of continuous use and monument building between about 3700 and 1600 BC.
The Statue of Liberty, United States
The Statue of Liberty was inscribed in 1984. According to UNESCO, it is a hollow colossus of thinly pounded copper sheets over a steel framework, standing on an island at the entrance to New York Harbor. It was designed by the sculptor Frederic Bartholdi in collaboration with the engineer Gustave Eiffel, and was a gift from France on the centenary of American independence in 1876. The pedestal was designed by the American architect Richard Morris Hunt, and the statue was dedicated in 1886.
Angkor, Cambodia
Inscribed in 1992, Angkor lies in Cambodia’s northern province of Siem Reap and extends over approximately 400 square kilometres. UNESCO says it consists of scores of temples, hydraulic structures and communication routes, and that for several centuries it was the centre of the Khmer Kingdom. Angkor Wat, the Bayon, Preah Khan and Ta Prohm are named as exemplars of Khmer architecture.
The Acropolis of Athens, Greece
Inscribed in 1987, the Acropolis is called by UNESCO the most striking and complete ancient Greek monumental complex still existing. It sits on a hill of average height (156 metres) in the basin of Athens, with overall dimensions of approximately 170 by 350 metres. UNESCO notes that fortification walls have surrounded the summit for more than 3,300 years, with the first wall built in the 13th century BC.
The Great Wall, China
Also inscribed in 1987, the Great Wall was, in UNESCO’s description, continuously built from the 3rd century BC to the 17th century AD on the northern border of China by successive empires, with a total length of more than 20,000 kilometres. It begins in the east at Shanhaiguan in Hebei province and ends at Jiayuguan in Gansu province to the west.
Putting landmark facts to work
A reliable approach for landmark questions is to anchor each site to three details: the country, the builder or civilisation, and the century. The facts above give that anchor for eight of the world’s best-known sites. For the full test, try the site’s landmark quizzes at three levels:
The bottom line
UNESCO’s World Heritage List gives quiz players a dependable, dated record for the world’s great landmarks. Knowing the inscription year, the builders and the defining detail of each site turns a vague hunch into a confident answer, and checking figures such as the total number of listed properties against the issuing body keeps those answers accurate.
