Kiambu wraps around northern Nairobi, rising from the Thika plains to the chilly Limuru highlands above the Rift Valley. It is Kenya's second most populous county, mixing coffee and tea estates with fast-growing towns.
Why it matters
Founding President Jomo Kenyatta's ancestral home is at Ichaweri. The 1953 Lari massacre was one of the darkest episodes of the Mau Mau war.
The economy
Kiambu has Kenya's second-largest county economy. Thika is an industrial centre, Tatu City is a special economic zone, and tea, coffee and dairy supply Nairobi and export markets.
