Abuja is the capital city of Nigeria. It is located in the center of Nigeria, within the Federal Capital Territory (FCT). Abuja, a planned city built in the 1980s, officially became Nigeria’s capital on December 12, 1991 replacing Lagos.
At the 2006 census, the city of Abuja had a population of 776,298 making it one of the ten most populous cities in Nigeria. Abuja is reported to be the fastest growing city in the world.
Abuja’s geography is defined by 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. Zuma Rock, a 792-metre monolith, lies just north of the city on the road to Kaduna State.
Other significant sights include the Nigerian National Mosque and the Nigerian National Christian Centre. The city is served by the Nnamdi Azikiwe International Airport. Abuja is known for being one of the few purpose-built capital cities in Africa as well as being one of the wealthiest.
