Mombasa (/mɒmˈbɑːsə/) is a city in the coast of Kenya along the Indian Ocean. It is the country’s oldest (circa 900 AD) and second-largest city (after the capital Nairobi), with an estimated population of about 1.5 million people in 2017. Its metropolitan region is the second largest in the country and has a population of approximately 3 million people. Administratively, Mombasa is the county seat of Mombasa County.
Mombasa is a regional cultural and economic hub; it has an extra-large port and an international airport and is an important regional tourism centre. Located on the east coast of Kenya, it also is the home of one of the State House (Kenya), and is considered by some as a second capital in all but name. In Mombasa County and the former Coast Province, Mombasa’s situation on the Indian Ocean made it a historical trading centre, and it has been controlled by many countries because of its strategic location.
