Addis Ababa is the capital of Ethiopia and, at roughly 2,355 metres, among the highest capital cities in the world. It has a population of something over three and a half million, it was founded only in 1886, and it hosts the headquarters of the African Union — which makes a young city the diplomatic centre of a continent.
A capital chosen for its hot springs
Ethiopia's court had been mobile for centuries, moving between temporary capitals as firewood and grazing were exhausted. Addis Ababa began as another of those camps.
Empress Taytu Betul, wife of Emperor Menelik II, favoured the site at Filwoha for its hot springs, and persuaded Menelik to settle there rather than on the cooler heights of Entoto above. She named it Addis Ababa — new flower, in Amharic — in 1886, and the court moved down permanently a few years later.
The choice was practical. Entoto, at over 3,000 metres, was cold, exposed and short of water. The site below was warmer, watered, and sat where several routes converged. What the new capital did not have was fuel.
The eucalyptus that saved it
Within a decade Addis Ababa was facing the same problem that had ended every previous Ethiopian capital: the surrounding hills had been stripped of wood for building and cooking, and the court was preparing to move again. Menelik had already begun laying out a replacement site.
The solution was imported. Eucalyptus, native to Australia, was introduced around the turn of the twentieth century and proved ideally suited — it grows extremely fast, coppices readily so it can be cut repeatedly without replanting, and tolerates the highland climate. Plantations spread across the hills above the city and supplied fuel and construction poles indefinitely.
Addis Ababa is therefore one of the few capital cities whose permanence rests on a single introduced tree species. The eucalyptus stands on Entoto are still there, still being cut, and the trade-offs are well known: the trees are thirsty, they suppress undergrowth, and they have displaced indigenous highland forest. They also stopped the capital moving, which is why the city exists.
Altitude changes everything
At around 2,355 metres, Addis Ababa is high enough that the climate bears almost no relation to what its latitude — roughly nine degrees north — would suggest. Instead of equatorial heat it has a mild, temperate regime with daytime temperatures typically in the high teens to low twenties Celsius year-round and genuinely cool nights.
Ethiopians describe their highland climate in terms of vertical zones rather than seasons, and Addis Ababa sits in the weyna dega band — the temperate middle. Rainfall is strongly seasonal, concentrated in the kiremt from June to September, when the city can be persistently wet and grey.
The altitude has a further consequence that has made the city internationally known in one specific field. Ethiopian distance runners train at these elevations, and the physiological advantages of growing up and training above 2,000 metres are a substantial part of why the country has dominated middle- and long-distance running for decades.
What Ethiopia's capital inherited
Addis Ababa is young, but the state it governs is not. Ethiopian polities trace back through the Solomonic dynasty, the medieval capitals at Gondar and Lalibela, and ultimately to Aksum, a trading empire that minted its own coinage and adopted Christianity in the fourth century — among the earliest states anywhere to do so.
That inheritance shows in the city's institutions: Holy Trinity Cathedral, where Haile Selassie is buried; St George's Cathedral, built to commemorate Adwa; and the Ethiopian Orthodox Tewahedo Church, which retains its own liturgy, calendar and canon and remains central to daily life for a large share of the population.
Why the African Union is here
Addis Ababa hosts the African Union, and before it the Organisation of African Unity, founded in the city in 1963. It also hosts the UN Economic Commission for Africa and a very large diplomatic community — by some counts the third or fourth largest concentration of diplomatic missions in the world.
The reason is historical rather than geographical. Ethiopia was the African state that was never colonised: it defeated an Italian invasion decisively at Adwa in 1896, and although Italy occupied the country from 1936 to 1941, it never established recognised sovereignty. When newly independent African states sought a headquarters in the early 1960s, Ethiopia's status as the continent's symbol of uncolonised sovereignty, and Haile Selassie's personal diplomacy, made Addis Ababa the natural choice.
That role shapes the city's built environment. The African Union's headquarters complex, funded and built by China and opened in 2012, is among the tallest buildings in the city, and the conference infrastructure, hotels and security apparatus around it exist to serve summitry.

Where human history is kept
The National Museum of Ethiopia holds the partial skeleton catalogued as AL 288-1 and known as Lucy — an Australopithecus afarensis individual roughly 3.2 million years old, found in the Afar region in 1974 and among the most important hominin fossils ever recovered.
The name comes from the Beatles song playing at the excavation camp; in Amharic she is Dinkinesh, meaning you are marvellous. What made the find so significant was completeness — around 40 per cent of a single skeleton — and the clear evidence it provided that bipedal walking preceded large brain size in human evolution.
Ethiopia's Afar and Omo regions have produced a remarkable share of the early hominin record, and the museum in Addis Ababa is where that material is curated. It is an odd and rather fitting distinction for a city founded in 1886 to be the custodian of three-million-year-old evidence.
Merkato, and how the city actually trades
Merkato, in the west of the city, is routinely described as the largest open-air market in Africa. Its origins are colonial: the Italian occupation administration relocated the indigenous market away from the centre in the 1930s under a segregationist plan, and the displaced market grew where it was put.
What it became is a vast informal commercial district rather than a market in the ordinary sense — tens of thousands of traders in a dense grid of alleys, organised into zones by trade, with a recycling quarter where scrap metal and plastics are worked into new goods. A large share of the city's employment is informal, and Merkato is where much of that economy is visible.
Coffee runs through it. Ethiopia is the plant's origin, and the domestic coffee ceremony — roasting, grinding and brewing in front of guests, served in three rounds — is a genuine social institution rather than a performance for visitors. Coffee is also the country's principal agricultural export, so the commodity that defines Ethiopian hospitality is also what pays for a large part of its imports.
A city of many languages
Amharic is the working language of the federal government and the lingua franca of the capital, written in the Ge'ez script — an abugida of over 200 characters that Ethiopia shares with Eritrea and that is unrelated to the Latin, Arabic or Cyrillic alphabets used across the rest of the continent.
But Addis Ababa is a migrant city, and Oromo, Tigrinya, Somali, Gurage and many others are spoken across its neighbourhoods. Ethiopia's federal structure organises regions on ethno-linguistic lines, which makes the capital — multi-ethnic, federally administered and geographically inside Oromia — structurally exceptional.
The country also keeps its own time and its own calendar. The Ethiopian calendar runs seven to eight years behind the Gregorian and has thirteen months; the clock starts counting at dawn rather than midnight, so what is 7 a.m. elsewhere is one o'clock in the morning locally. Both are in everyday use, and both catch visitors out. Our guide to how many countries there are in the world covers Ethiopia's unusual position as the state that was never colonised.
Building upward and outward
Addis Ababa has changed physically faster in the last two decades than in its first century. The Addis Ababa Light Rail, opened in 2015, was the first light rail system in sub-Saharan Africa, built with Chinese finance and construction. The Addis Ababa–Djibouti railway, electrified and completed shortly afterwards, replaced a colonial-era French line and gives landlocked Ethiopia its principal freight link to the sea.
The city's older fabric has been substantially cleared in the process. Large areas of low-rise informal housing, including much of the Merkato district's surroundings — Merkato being widely described as one of the largest open-air markets in Africa — have been redeveloped into condominium blocks and boulevards. The rehousing has been contested, and the displacement of long-established communities is the standard criticism of the programme.
Underneath the construction sits an unresolved political question. Addis Ababa is a federal city, but it is geographically surrounded by the Oromia region, and the constitutional status of Oromia's interest in the capital — and the displacement of Oromo farmers by the city's expansion — has been one of the most persistent flashpoints in modern Ethiopian politics.
