Abuja

Abuja's geography is defined by Aso Rock, a 400-metre (1,300 ft) monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court, and much of the city extends to the south of the rock. Zuma Rock, a 725-metre (2,379 ft) monolith, lies just north of the city on the expressway to Kaduna.

At the 2006 census, the city of Abuja had a population of 776,298 and 179,674 households, making it one of the ten most populous cities in Nigeria (eighth place in 2006). According to the United Nations, Abuja grew by 139.7% between 2000 and 2010, making it the fastest-growing city in the world. As of 2015, the city is experiencing an annual growth of at least 35%, retaining its position as the fastest-growing city on the African continent and one of the fastest-growing in the world.

Major religious sites include the Nigerian National Mosque and the Nigerian National Christian Centre. The city is served by the Nnamdi Azikiwe International Airport.
