Chichén Itzá (often spelled Chichen Itza in English and traditional Yucatec Maya) was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archeological site is located in Tinúm Municipality, Yucatán State, Mexico.

Chichén Itzá was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the Northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.

Christ the Redeemer (Portuguese: Cristo Redentor, standard Brazilian Portuguese: [ˈkɾistu ʁedẽˈtoʁ]) is an Art Deco statue of Jesus in Rio de Janeiro, Brazil, created by French-Polish sculptor Paul Landowski and built by Brazilian engineer Heitor da Silva Costa, in collaboration with French engineer Albert Caquot. Romanian sculptor Gheorghe Leonida sculpted the face. Constructed between 1922 and 1931, the statue is 30 metres (98 ft) high, excluding its 8-metre (26 ft) pedestal. The arms stretch 28 metres (92 ft) wide. It is made of reinforced concrete and soapstone. Christ the Redeemer differs considerably from its original design, as the initial plan was a large Christ with a globe in one hand and a cross in the other. Although the project organizers originally accepted the design, it later changed to the statue of today, with the arms spread out wide.

The statue weighs 635 metric tons (625 long, 700 short tons), and is located at the peak of the 700-metre (2,300 ft) Corcovado mountain in the Tijuca National Park overlooking the city of Rio de Janeiro. This statue is the largest Art Deco–style sculpture in the world. A symbol of Christianity around the world, the statue has also become a cultural icon of both Rio de Janeiro and Brazil and was voted one of the New 7 Wonders of the World.

Machu Picchu is a 15th-century Inca citadel located in the Eastern Cordillera of southern Peru on a mountain ridge at 2,430 meters (7,970 ft). Often referred to as the "Lost City of the Incas", it is the most familiar icon of the Inca Empire. It is located in the Machupicchu District within the Urubamba Province above the Sacred Valley, which is 80 kilometers (50 mi) northwest of the city of Cusco. The Urubamba River flows past it, cutting through the Cordillera and creating a canyon with a subtropical mountain climate.

The Inca civilization had no written language and following the first encounter by the Spanish soldier Baltasar Ocampo, no Europeans are recorded to have visited the site from the late 16th century until the 19th century. As far as historical knowledge extends, there are no existing written records detailing the site during its period of active use. The leading theory is that Machu Picchu was a private city for Incan royalty. The names of the buildings, their supposed uses, and their inhabitants, are the product of modern archaeologists based on physical evidence, including tombs at the site. Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary structures are the Temple of the Sun, the Temple of the Three Windows, and the Intihuatana. From 1929 to 1971, Machu Picchu underwent extensive restoration and conservation work, including structural stabilization and artifact excavation, driven by government initiatives and research expeditions. Most recent archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438–1472). The Inca built the estate around 1450 but abandoned it a century later, at the time of the Spanish conquest. According to the new AMS radiocarbon dating, it was occupied from c. 1420–1532. Historical research published in 2022 claims that the site was probably called Huayna Picchu by the Inca people themselves, as it exists on the smaller peak of the same name.

Machu Picchu was declared a Peruvian Historic Sanctuary in 1982 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide internet poll.

Petra (Arabic: ٱلْبَتْراء, romanized: Al-Batrāʾ; Ancient Greek: Πέτρα, "Rock"), originally known to its inhabitants as Raqmu (Nabataean: 𐢛𐢚𐢒‎ or 𐢛𐢚𐢓𐢈‎, *Raqēmō), is a historic and archaeological city in southern Jordan. Famous for its rock-cut architecture and water conduit systems, Petra is also called the "Rose City" because of the colour of the sandstone from which it is carved. The city is one of the New 7 Wonders of the World and a UNESCO World Heritage Site.

The area around Petra has been inhabited from as early as 7000 BC, and was settled by the Nabataeans, a nomadic Arab people, in the 4th century BC. Petra would later become the capital city of the Nabataean Kingdom in the second century BC. The Nabataeans invested in Petra's proximity to the incense trade routes by establishing it as a major regional trading hub, which gained them considerable revenue. Unlike their enemies, the Nabataeans were accustomed to living in the barren deserts and thus were able to defend their kingdom. They were particularly skillful in agriculture, stone carving, and rainwater harvesting.

Petra flourished in the 1st century AD, when its Al-Khazneh structure, possibly the mausoleum of Nabataean king Aretas IV, was constructed, and its population peaked at an estimated 20,000 inhabitants. Nabataea fell to the Romans in 106 AD, who annexed and renamed it as Arabia Petraea. Petra's importance declined as sea trade routes emerged, and after an earthquake in 363 destroyed many structures. In the Byzantine era, several Christian churches were built, but the city continued to decline and, by the early Islamic era, it was abandoned except for a handful of nomads. It remained unknown to the western world until 1812, when Swiss traveller Johann Ludwig Burckhardt rediscovered it.

UNESCO has described Petra as "one of the most precious cultural properties of man's cultural heritage". Petra is a symbol of Jordan, as well as Jordan's most-visited tourist attraction. Visitor numbers reach close to a million tourists every year.

The Taj Mahal (/ˌtɑːdʒ məˈhɑːl, ˌtɑːʒ -/ TAHJ mə-HAHL, TAHZH -⁠, Hindi: [taːdʒ ˈmɛɦ(ɛ)l]; lit. 'Crown of the Palace') is an ivory-white marble mausoleum on the right bank of the river Yamuna in Agra, Uttar Pradesh, India. It was commissioned in 1631 by the fifth Mughal emperor, Shah Jahan (r. 1628–1658) to house the tomb of his beloved wife, Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. The tomb is the centrepiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall.

Construction of the mausoleum was completed in 1648, but work continued on other phases of the project for another five years. The first ceremony held at the mausoleum was an observance by Shah Jahan, on 6 February 1643, of the 12th anniversary of the death of Mumtaz Mahal. The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be around ₹5 million, which in 2023 would be approximately ₹35 billion (US$77.8 million).

The building complex incorporates the design traditions of Indo-Islamic and Mughal architecture. It employs symmetrical constructions with the usage of various shapes and symbols. While the mausoleum is constructed of white marble inlaid with semi-precious stones, red sandstone was used for other buildings in the complex similar to the Mughal era buildings of the time.

The Taj Mahal was designated as a UNESCO World Heritage Site in 1983 for being "the jewel of Islamic art in India and one of the universally admired masterpieces of the world's heritage". It is regarded as one of the best examples of Mughal architecture and a symbol of Indian history. The Taj Mahal is a major tourist attraction and attracts more than five million visitors a year. In 2007, it was declared a winner of the New 7 Wonders of the World initiative.
