Lagos
largest city and former capital of Nigeria
Lagos (; LAY-goss; Yoruba: Èkó [èkó]), or Lagos City, is a large metropolitan port city in southwestern Nigeria. As of November 2025, the size of the city's population has been estimated to be between 17 and 21 million residents, making Lagos the largest city in Nigeria, the most populous urban area on the African continent, and one of the fastest-growing megacities in the world.
The lands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while being protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 kilometres (62 mi) east and west of the mouth.
With its international airport, three ports (Apapa, Tin Can Island and Lekki deep-sea port), four expressways (to Badagry, Abeokuta, Ibadan and Calabar, the latter under construction since 2023 and partially operational in 2026), and the standard-gauge rail link to Abeokuta and Ibadan, the city is well connected in terms of transport and handles 88% of Nigeria’s exports. The urban rail transit system in Lagos is regarded as one of the most modern of its kind in Africa.
Lagos is best known as the leading financial centre of West and Central Africa, with headquarters of financial institutions like Access Bank, the First Bank of Nigeria or Zenith Bank. The Nigerian Exchange Group, the main stock exchange group in Nigeria, is also located here. Other major employers include two breweries, three major shipyards and the headquarters of several African airlines. Lagos is also home to numerous pharmaceutical companies; the city is also an exhibition city: Art X Lagos is West Africa’s largest art fair, whilst Lagos Fashion Week is Africa’s largest fashion fair. It has more than 20 data centres in operation and branches of Microsoft, Equinix and Google.
This brief starts where responsible research should: with the source description of “Lagos” as largest city and former capital of Nigeria. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as largest city and former capital of Nigeria. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 27, 2026. The linked authority identifier is Q8673. VIAF identifies the subject as 154757661. The Library of Congress control number is n79066730. Authority coordinates are 6.456, 3.394. 5 of 6 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025, 2023 and 2026.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
