Lagos is the largest city in Nigeria and the African continent. It is also the second fastest growing “city” on the continent and one of the most populous urban agglomerations in the world. Lagos is a major financial centre in Africa; the mega city has the highest GDP and also houses one of the largest and busiest ports on the continent.
Lagos initially emerged as a port city which originated on a collection of islands. Due to rapid urbanization, the city expanded to the west of the lagoon to include areas in the present day Lagos Mainland. This led to the classification of Lagos into two main areas – the Island, which was the initial city of Lagos, before it expanded into the area known as the Mainland.
