The city is here because the train could not climb the hill.

In 1899 the Uganda Railway needed a supply depot before tackling the climb up the Limuru escarpment, and picked the last flat ground left: a swamp at 1,795 metres with cold water and a temperate climate. The Maasai called it the place of cool waters. That siding is today a city of 5.6 million people.

01 A supply depot

The site was identified by the railway's chief engineer, and the reasons cited read like a manual: high elevation, temperate climate and an adequate water supply. None of that has anything to do with founding a city. Those are the requirements of a railway store.

And one detail makes the decision more improbable still: the ground was swampland. A wetland was chosen, with all the drainage problems that implies, because it was flat and because it sat just before the gradient. The city was built afterwards, on top, solving as it went what the site did not provide.

A very wide panorama of the city taken from height: from side to side stretches a dense urban fabric of buildings of varying heights, with some twenty white and grey office towers standing out above a continuous base of lower construction and trees pushing between the blocks; the whole flattens towards the back, where the city dissolves into a blue-grey haze with no visible relief; the sky, in the upper band, is covered by a uniform layer of pale cloud, without sun.

02 The place of cool waters

The name predates the railway and describes precisely what the engineer was after. In Maa, the Maasai language, the phrase Nairobi derives from means "place of cool waters", after the cold stream that ran through the area. The place name is a hydrological description, and that description is what made the depot viable.

Altitude is the other factor, and it still explains the city every day. Nairobi sits at 1,795 metres and a little over one degree south of the equator. That combination produces a climate nothing like what you expect of the latitude: mean highs between 22 and 27.7 degrees all year, and nights that drop to 9.2 in July.

Sunrise over a plain of tall dry grass: the sun, a white, sharply defined disc, has just lifted off the horizon on the left of the frame and floods the whole sky with a gradient running from intense orange below to pale pink above, without a single cloud; at mid-height, a layer of low horizontal mist floats just above the ground and wraps the base of a line of small flat-crowned trees standing out in silhouette; the foreground is grass, dark and bristling with seed heads, and nothing else.

03 From swamp to five million

The jump in scale is among the largest anyone can document. From a railway depot set up in 1899 to a city of 5.6 million people, with a metropolitan area of around sixteen million. In little more than a century, and without any of the factors that usually explain a city that size.

That leaves a capital without a historic centre in the usual sense. What sits at Nairobi's heart is an office district built mostly from the second half of the twentieth century onwards: ten- to twenty-storey towers, streets too narrow for the traffic they carry, and very high density across a few blocks.

A view of the downtown cluster of high-rises taken from mid-height: some twenty office towers of different periods and heights group at the centre of the frame, with façades of bluish glass, white concrete and grey panelling, one of them topped by a cylindrical crown; between the towers appear lower buildings, cranes and rooftop tanks; to the sides and in the foreground, trees and lower construction drop the profile abruptly; at the back, the city spreads flat until it fades into pale haze, under a whitish sky.

04 How to visit it

By area, and allowing for traffic, which is the great constraint. The office district is walkable in a morning; the rest of the city is very spread out and internal journeys eat far more time than the map suggests. Two stops a day is a realistic plan; four is not.

The second warning is architectural expectation. There is no colonial ensemble to tour here and no old quarter, because the city is little more than a century old and grew fast and in jumps. What there is is a very live urban scene — restaurants, music, markets — that works far better than any list of sights.

And the third is what really sets this capital apart: open country begins inside the municipal boundary. A few kilometres from the office district there is savanna with lions and rhinoceroses, and that frontier — a fence, and the city on the other side of it — is the image that sums up Nairobi better than any other.
