New national capital with ecological structure
Abuja's 1979 master plan, devised to replace overcrowded, ethnically charged Lagos as Nigeria's capital, laid out a new monumental administrative city on a crescent plan with zoned districts and a central axis terminating at Aso Rock.
Abuja is a major example of late-20th-century capital relocation and nation-building in Africa, intended as neutral common ground for a diverse federation — and a case study in the gap between master-plan ideals and lived reality.
Realised: Abuja replaced Lagos as Nigeria's capital on 12 December 1991 and has grown rapidly, though largely beyond the planned core.
Strict, costly plan controls priced out lower-income residents, spawning extensive informal settlements on the city's fringes.
