The capital of Nigeria is Abuja. Established as the capital in 1991, Abuja was chosen due to its central location, making it more accessible from various regions of the country. It was designed to be a modern city and to alleviate congestion in Lagos, Nigeria's former capital. Abuja features various government buildings, international embassies, and cultural institutions. One of its most notable landmarks is the Aso Rock, a prominent rock formation near the Presidential Complex. The city's development is reflective of Nigeria's growth and ongoing efforts to establish a unified national identity amidst diverse cultures.
