City history
Founded in 1899 as a railway camp at a Maasai watering place, Nairobi evolved into Kenya's capital, keeping year-round East Africa Time anchored by iconic civic clock towers.
Chapter one
Indigenous name
"Place of cool waters"
Long before colonial settlement, pastoralist Maasai people named the cool stream and swampy water hole 'Enkare Nyrobi'. When the British Uganda Railway established a rail depot here in 1899, engineers adapted the name into 'Nairobi'.
Place of cool waters
Original Maasai name for the cold stream and wetland where pastoralists watered their cattle.
Anglicized railway depot name
Established as Mile 327 on the Uganda Railway in 1899, becoming capital of the British East Africa Protectorate in 1905.
Administrative municipal designation
Declared a municipality in 1919 as commercial and administrative infrastructure rapidly expanded around the central rail hub.
Capital city of Kenya
Granted royal city status in 1954, remaining the national capital after Kenya achieved independence in 1963.
Chapter two
When the Uganda Railway reached Nairobi in May 1899, local mean solar time (approximately UTC+02:27) governed rail camp schedules.
British East Africa synchronized rail lines across Kenya and Uganda by adopting GMT+3 (UTC+3) standard time.
The colonial government adjusted standard time to GMT+2:30, known as British East Africa Time, for regional alignment.
Standard time in Kenya was adjusted to GMT+2:45 during World War II military and administrative coordination.
Kenya returned permanently to UTC+3 (East Africa Time), maintaining constant year-round standard time without daylight saving shifts.
Chapter three
The Uganda Railway reached Mile 327 at Enkare Nyrobi in May 1899, establishing headquarters and workshops that created the settlement.
British East Africa transferred its capital from coastal Mombasa to inland Nairobi, establishing the city as the political headquarters.
Architect Amyas Connell completed the Legislative Buildings featuring an English-style clock tower requested by colonial leaders to evoke Big Ben.
The new Nairobi City Hall opened with a 165-foot clock tower, making it the tallest building in Nairobi upon its completion in 1957.
Kenya achieved independence on December 12, 1963, designating Nairobi as the national capital and diplomatic hub of East Africa.
