Mombasa County in the context of "Nairobi City County"

Mombasa (/mɒmˈbæsə/ mom-BASS-ə; also US: /-ˈbɑːsə/ -⁠BAH-sə) is a coastal city in southeastern Kenya along the Indian Ocean. It was the first capital of British East Africa, before Nairobi was elevated to capital status in 1907. It now serves as the capital of Mombasa County. Buildings in the CBD are blue and white, representing the Indian Ocean. It is the country's oldest (c. 900 A.D.) and second-largest city after Nairobi, with a population of about 1,208,333 people according to the 2019 census.

Mombasa's location on the Indian Ocean made it a historical trading centre, and it has been controlled by many countries because of its strategic location. Kenyan school history books place the founding of Mombasa as 900 AD. It must have been already a prosperous trading town in the 12th century, as the Arab geographer al-Idrisi mentions it in 1151. It was a part of the Kilwa Sultanate from approximately the early 14th century until the dissolution of the sultanate in 1513. The oldest stone mosque in Mombasa, Mnara, was built c. 1300. The Mandhry Mosque, built in 1570, has a minaret that contains a regionally specific ogee arch. The city later came under the occupation and control of the Omani Empire in the late 17th century.

The Old Town of Mombasa, also known as Mji Wa Kale, is the old part of Mombasa, the main city of Mombasa County in Kenya. Situated on the south-east side of Mombasa Island, the Old Town covers an area of 72 hectares (180 acres), and is inhabited by a mix of Swahili, Arab, Persian, Indian, Asian, Portuguese and British settlers.

In 1997, the Old Town and Fort Jesus were submitted by the National Museums of Kenya for selection in UNESCO's list of World Heritage Sites.
