It has served as a harbor for boats for many years.

It has two of the most important ports in the country, one of which is the city of Cienfuegos, the capital of the province.

On his second voyage to the Americas, Christopher Columbus visited the bay in 1494.

The Jagua Fortress was erected by King Philip V of Spain in 1742 to protect the bay from pirates who prowled the Caribbean coast in those days.

They used it as a refuge at landfall, on their way to the city of Cienfuegos.
