In geography, the antipodes ( //; from Greek: ἀντίποδες, from anti- "opposed" and pous "foot") of any place on Earth is the point on the Earth's surface which is diametrically opposite to it. Two points that are antipodal (//) to one another are connected by a straight line running through the centre of the Earth.
In the British Isles, "the Antipodes" is often used to refer to Australia and New Zealand, and "Antipodeans" to their inhabitants. Geographically the antipodes of the British Isles are in the Pacific Ocean, south of New Zealand. This gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipodes of London at about 50° S 179° E. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, and Morocco are antipodal to New Zealand. The antipodes of South Africa and Zimbabwe are in the North Pacific Ocean, with Botswana antipodal to Hawaii, though as Southern Hemisphere ex-British colonies, they are sometimes included as antipodeans in colloquial English.
All together, less than 4% of land is antipodal to land. The largest antipodal land masses are the Malay Archipelago, antipodal to the Amazon Basin and adjoining Andean ranges; east China and Mongolia, antipodal to Chile and Argentina; and Greenland and the Canadian Arctic Archipelago, antipodal to East Antarctica.
The antipodes of any place on the Earth is the place that is diametrically opposite it, so a line drawn from the one to the other passes through the centre of the Earth and forms a true diameter. For example, the antipodes of New Zealand's lower North Island lies in Spain. Most of the Earth's land surfaces have ocean at their antipodes, this being a consequence of most land being in the land hemisphere.
The antipodes of any place on Earth are distant from it by 180° of longitude and as many degrees to the north of the equator as the original is to the south (or vice versa); in other words, the latitudes are numerically equal, but one is north and the other south. The map shown above is based on this relationship; it shows a Lambert azimuthal equal-area projection map of the Earth, in pink, overlaid on which is another map, in blue, shifted horizontally by 180° of longitude and inverted about the equator with respect to latitude.
Noon at the one place is midnight at the other (ignoring daylight saving and irregularly shaped time zones) and, with the exception of the tropics, the longest day at one point corresponds to the shortest day at the other, and midwinter at one point coincides with midsummer at the other.
If the geographic coordinates (latitude and longitude) of a point on the Earth’s surface are (φ, θ), then the coordinates of the antipodal point are (−φ, θ ± 180°). This relation holds true whether the Earth is approximated as a perfect sphere or as a reference ellipsoid.
In terms of the usual way these geographic coordinates are given, this transformation can be expressed symbolically as
- x° N/S y° E/W ↦ x° S/N (180 − y)° W/E,
that is, for the latitude (the North/South coordinate) the magnitude of the angle remains the same but N is changed to S and vice versa, and for the longitude (the East/West coordinate) the angle is replaced by its supplementary angle while E is exchanged for W. For example, the antipodes of the point in China at 37° N 119° E (a few hundred kilometres from Beijing) is the point in Argentina at 37° S 61° W (a few hundred kilometres from Buenos Aires).
For if there were any solid body in equipoise at the centre of the universe, there would be nothing to draw it to this extreme rather than to that, for they are all perfectly similar; and if a person were to go round the world in a circle, he would often, when standing at the antipodes of his former position, speak of the same point as above and below; for, as I was saying just now, to speak of the whole which is in the form of a globe as having one part above and another below is not like a sensible man.
The term is taken up by Aristotle (De caelo 308a.20), Strabo, Plutarch and Diogenes Laertius, and was adopted into Latin as antipodes. The Latin word changed its sense from the original "under the feet, opposite side" to "those with the feet opposite", i.e. a bahuvrihi referring to hypothetical people living on the opposite side of the Earth. Medieval illustrations imagine them in some way "inverted", with their feet growing out of their heads, pointing upward.
Yonde in Ethiopia ben the Antipodes, men that haue theyr fete ayenst our fete.
(In Modern English: Yonder in Ethiopia are the Antipodes, men that have their feet against our feet.)
From the time of St Augustine, the Christian church was sceptical of the notion of the idea of the Antipodes. Augustine asserted that "it is too absurd to say that some men might have set sail from this side and, traversing the immense expanse of ocean, have propagated there a race of human beings descended from that one first man."
In the Early Middle Ages, Isidore of Seville's widely read encyclopedia presented the term "antipodes" as referring to antichthones (people who lived on the opposite side of the Earth), as well as to a geographical place; these people came to play a role in medieval discussions about the shape of the Earth. In 748, Pope Zachary declared belief in the antipodes, as apparently held by Vergilius of Salzburg, to be heretical. The antipodes being an attribute of a spherical Earth, some authors used their perceived absurdity as an argument for a flat Earth. However, knowledge of the spherical Earth was widespread during the Middle Ages, only occasionally disputed on theological grounds. The medieval dispute surrounding the antipodes mainly concerned the question whether people could live on the opposite side of the earth: since the torrid clime was considered impassable, it would have been impossible to evangelize them, posing a dilemma between two equally unacceptable possibilities that either Christ had appeared a second time in the antipodes, or that the people there were irredeemably damned. Such an argument was forwarded by the Spanish theologian Alonso Tostado as late as the 15th century and "St. Augustine doubts" was a response to Columbus's proposal to sail westwards to the Indies.
The author of the Norwegian book Konungs Skuggsjá, from around 1250, discusses the existence of antipodes. He notes that (if they exist) they will see the sun in the north in the middle of the day and that they will have opposite seasons of the people living in the Northern Hemisphere.
The earliest surviving account by a European who had visited the Southern Hemisphere is that of Marco Polo (who, on his way home in 1292, sailed south of the Malay Peninsula). He noted that it was impossible to see the star Polaris from there.
The idea of dry land in the southern climes, the Terra Australis, was introduced by Ptolemy and appears on European maps as an imaginary continent from the 15th century. In spite of having been discovered relatively late by European explorers, Australia was inhabited very early in human history, the ancestors of the Indigenous Australians having reached it at least 50,000 years ago.
List of antipodes
Around 71% of the Earth's surface is covered by oceans, and seven-eighths of the Earth's land is confined to the land hemisphere, so the majority of locations on land do not have land-based antipodes.
The two largest human inhabited antipodal areas are located in East Asia (mainly eastern China) and South America (mainly northern Argentina and Chile). The Australian mainland is the largest landmass with its antipodes entirely in ocean.
Exact or almost exact antipodes:

Cities and geographic features
Gibraltar is approximately antipodal to Te Arai Beach about 85 km north of Auckland, New Zealand. This illustrates the old bromide that the sun never sets on the British Empire, however the sun still does not set on the British Commonwealth.
The northern part of New Caledonia, an overseas territory of France, is antipodal to some thinly populated desert in Mauritania, a part of the former French West Africa. Portions of Suriname, a former Dutch colony, are antipodal to Sulawesi, an Indonesian island known as Celebes when it was part of the Netherlands East Indies. Luzon Island in the Philippines is antipodal to Eastern Bolivia. As with the British Empire, the sun did not set on the French Empire or the Dutch Empire or the Spanish Empire at their peaks.
South Georgia Island is antipodal to the northernmost part of Sakhalin Island.
As can be seen on the purple/blue map, the Pacific Ocean is so large that it stretches halfway around the world; parts of the Pacific off the coast of Peru are antipodal to parts of the same ocean off the coast of Southeast Asia.
The following countries are opposite more than one other country. (Antarctica is considered separately from any territorial claims.)
Countries matching up with just one other country are Morocco, Spain, Portugal (all with New Zealand); Chad, Libya, Cameroon (with the Cook Islands of New Zealand); Egypt, Eritrea, Ethiopia (with French Polynesia); Senegal (Vanuatu); UAE (Pitcairn); Ghana, Ivory Coast (Tuvalu); Burkina Faso (Rotuma in Fiji); Guinea (Solomon Islands); India (Easter Island); Laos, Cambodia, Vietnam, and Thailand (all with Peru); Singapore (Ecuador); Brunei, Palau, Micronesia (all with Brazil).
Of these, the larger countries which are entirely antipodal to land are the Philippines, Malaysia, Taiwan, Fiji, Vanuatu, Brunei, and Samoa. Chile was as well prior to its expansion into the Atacama with the War of the Pacific.

In popular culture
- In 2006, Ze Frank challenged viewers of his daily webcast the show with zefrank to create an "Earth sandwich" by simultaneously placing two pieces of bread at antipodal points on the Earth's surface. The challenge was successfully completed by viewers in Spain and New Zealand.
- The May 19, 2008, official Lost audio podcast gave credence to a theory that the Island (the setting of the show) is located at Tunisia's antipode, in the south Pacific east of New Zealand.
- On the popular TV show Angel, the Deeper Well is a hole that goes through the world, with its entrance in The Cotswolds in England and its antipode in New Zealand.
- New Zealand writer Mark Price undertook a tour in 2005–06 of the length of New Zealand and its land antipodes in Morocco and Spain, from Kerikeri (near Larache and Lixus, Morocco ) to Cathedral Square, Christchurch (near Foz, Spain ).
- An episode of the fourth series of the science fiction television series Torchwood inaccurately refers to Shanghai and Buenos Aires as being antipodes of each other. However, some websites claim that they are approximate antipodes, and Shanghai's antipode is Salto, Uruguay some 220 miles (350 km) to the north of Buenos Aires.
- A common misconception, often expressed in pop culture, is that if one were to burrow through the earth from the United States, one would end up in China. In fact only portions of South America are antipodes with China. The scientific term China Syndrome takes its name (though not its concept) from this misconception.
