Abuja is Nigeria's administrative and political capital, strategically located at the crossroads of Nigeria's ethnic and religious groups. The diverse architecture of the city is reflected in notable sites including the Nigerian National Mosque, National Assembly, Supreme Court and National Stadium. As you approach the city’s Nnamdi Azikiwe International Airport, the impressive Aso Rock rises majestically over the city's central government district. Abuja is known for being one of the few purpose-built capital cities in Africa, as well as being one of the wealthiest. It is also a key capital on the African continent due to Nigeria's geo-political influence in regional affairs.
