Абуджа is the capital city of Nigeria, located in the center of the country. It was officially designated as the capital in 1991, replacing Lagos due to its more central location, which makes it more accessible to people from different regions. The city is known for its modern architecture and well-planned layout, featuring wide roads and green spaces. The city is home to several important government buildings, including the Nigerian National Assembly and the Presidential Complex. A significant landmark in Abuja is the Aso Rock, a large rock formation that overlooks the city. Abuja also hosts various cultural and religious institutions, reflecting the diverse population of Nigeria.
