The first item in this list, Bolivia, is a country with multiple capitals, La Paz and Sucre. La Paz is the seat of the government and Sucre is the constitutional capital. If La Paz is considered the national capital of Bolivia, then it is ranked number one in the list. However, if Sucre is specified, then Ecuador's capital, Quito, is the national capital at the highest altitude.

Rogun Dam is an embankment dam under construction on the Vakhsh River in southern Tajikistan. It is one of the planned hydroelectric power plants of Vakhsh Cascade. Over three decades only preliminary construction has been carried out on the dam. Due to its controversial state, construction was suspended in August 2012 pending World Bank reports, but has since then resumed. The dam has drawn complaints from neighbor Uzbekistan, which fears it will negatively impact its lucrative cotton crops. The dispute over the project has contributed significantly to bitter relations between the two former Soviet republics.

This project is under construction, opening date is 2018.

Nurek Dam is 300 m. high and it is the second highest Dam in the world.

Angel Falls is a waterfall in Venezuela. It is the world's highest uninterrupted waterfall, with a height of 979 meters (3,212 ft) and a plunge of 807 meters (2,648 ft). The waterfall drops over the edge of the Auyán-tepui mountain in the Canaima National Park, a UNESCO World Heritage site in the Gran Sabana region of Bolívar State. The height figure 979 meters (3,212 ft) mostly consists of the main plunge but also includes about 400 meters (0.25 mi) of sloped cascade and rapids below the drop and a 30-metre (98 ft) high plunge downstream of the talus rapids.

The giraffe (Giraffa) is a genus of African even-toed ungulate mammals, the tallest living terrestrial animals, and the largest ruminants. The genus currently consists of one species, Giraffa camelopardalis, the type species. Seven other species are extinct, prehistoric species known from fossils. Taxonomic classifications of one to eight extant giraffe species have been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Giraffa, but the IUCN currently recognizes only one species with nine subspecies.

Daocheng Yading Airport (IATA: DCY, ICAO: ZUDC) is an airport serving Daocheng County in the Garzê Tibetan Autonomous Prefecture of Sichuan Province, China. It is located in Sangdui Township, 50 kilometers north of the county seat and 130 kilometers from the Yading Nature Reserve.

At 4,411 m (14,472 ft) above sea level, Daocheng Yading is the world's highest civilian airport, surpassing the previous record holder Qamdo Bamda Airport, in Tibet, at 4,334 m (14,219 ft).

Well, the altitude is impressive – 6,390m above sea level. But the lake itself is another small crater lake, with a diameter of only 100m and a depth of 10m. It doesn’t even have its own name, just taking the name of the volcano it sits upon – Ojos del Salado, or “The Eyes of Salty Water” in English. It’s the highest volcano on Earth and is not entirely dormant, having had some recent volcanic activity such as sulfuric gases and vapors leaking out.

Tokyo Skytree is a broadcasting, restaurant, and observation tower in Sumida, Tokyo, Japan. It became the tallest structure in Japan in 2010 and reached its full height of 634.0 metres (2,080 ft) in March 2011, making it the tallest tower in the world, displacing the Canton Tower, and the second tallest structure in the world after the Burj Khalifa (829.8 m/2,722 ft).

The tower is the primary television and radio broadcast site for the Kant? region; the older Tokyo Tower no longer gives complete digital terrestrial television broadcasting coverage because it is surrounded by high-rise buildings.

Mount Everest, also known in Nepali as Sagarmatha and in Tibetan as Chomolungma, is Earth's highest mountain. The current official height of 8,848 m (29,029 ft), recognised by China and Nepal, was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 2005, China remeasured the rock height of the mountain, with a result of 8844.43 m. There followed an argument between China and Nepal as to whether the official height should be the rock height (8,844 m., China) or the snow height (8,848 m., Nepal). In 2010, an agreement was reached by both sides that the height of Everest is 8,848 m, and Nepal recognises China's claim that the rock height of Everest is 8,844 m.
