Abuja is the capital city of Nigeria, with an estimated population of 1.8 million.
Abuja's feature is Aso Rock, a 400-metre monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the town extend to the south of the rock. "Aso" means "victorious" in the language of the (now displaced) Asokoro ("the people of victory").
Other sights include the Nigerian National Mosque and the National Ecumenical Centre cathedral. The city is served by the Nnamdi Azikiwe International Airport, while Zuma Rock lies nearby.
