The capital city of Nigeria is Abuja. Established as the capital in 1991, it replaced Lagos due to reasons of overpopulation and infrastructure challenges. Abuja was chosen for its central location, aiming to provide a more accessible and neutral ground for Nigeria's diverse ethnic groups. The city features modern architecture, government institutions, and diplomatic missions, contributing to its role as Nigeria's political center. Notable landmarks in Abuja include the Aso Rock, the Nigerian National Mosque, and the Nigerian National Christian Centre. The city's planned layout and development reflect Nigeria's ambitions for growth and modernization.
