Conquistador Diego Velázquez de Cuéllar founded Havana on August 25, 1515, on the southern coast of the island, near the present town of Surgidero de Batabanó, or more likely on the banks of the Mayabeque River close to Playa Mayabeque. All attempts to found a city on Cuba's south coast failed. However, an early map of Cuba drawn in 1514 places the town at the mouth of this river.
