Lagos and Victoria Island. Three major bridges join the island to the mainland. They are the Carter Bridge, which starts from Iddo; the Eko Bridge (formerly called the Second Mainland Bridge); and the Third Mainland Bridge, which passes through densely populated mainland suburbs to the Lagos Lagoon. Lagos Island contains a central business district. This district is characterised by high-rise buildings. The island also contains many of the city's largest wholesale marketplaces (such as the popular Idumota and Balogun Markets). It also has the National Museum of Nigeria, the Central Mosque, the Glover Memorial Hall, Christ's Church Cathedral (CMS) and the
Lagos Consul and was located at Wydah. At the time of Beecroft's appointment, the Kingdom of Lagos (under Oba Kosoko) was in the western part of the Consulate of the Bights of Benin and Biafra and was a key slave trading port. In 1851 and with pressure from liberated slaves who now wielded political and business influence, Britain intervened in Lagos in what is now known as the Bombardment of Lagos or Capture of Lagos resulting in the installation of Oba Akitoye and the ouster of Oba Kosoko. Oba Akitoye then signed the Treaty between Great Britain and Lagos abolishing slavery.
