Overview Lying on Lagos Lagoon, a large protected harbour on the coast of Africa, the island is home to the Yoruba fishing village of Eko, which grew into the modern city of Lagos. The city has now spread out to cover the neighboring islands as well as the adjoining mainland. Lagos Island is connected to the mainland by three large bridges (the Carter Bridge, the Eko Bridge and the Third Mainland Bridge) which cross Lagos Lagoon to the district of Ebute Metta. It is also linked to the neighboring island of Ikoyi and to Victoria Island. The Lagos harbor district of Apapa faces the western side of the island. Forming the main commercial district of Lagos, Lagos Island plays host to the main government buildings, shops and offices. The Catholic and Anglican Cathedrals, as well as the Central Mosque, are located here.
