Ikoyi
Ikoyi is the most affluent neighborhood of Lagos, located in Eti-Osa Local Government Area. It lies to the northeast of Obalende and adjoins Lagos Island to the west, and at the edge of the Lagos Lagoon . Popular with the upper class residents of Nigerian society, Ikoyi is arguably the wealthiest community within Lagos State.
The area that makes up Ikoyi was originally a continuous land mass with Lagos Island, until it was separated from by a narrow waterway that was dug by the British colonial government. This canal has now been built over or filled so that the island is fused with Lagos Island once again.
