The bay of Havana is one of the largest and safest bays in America and the world, in the form of a bag, which gives security to the ships it welcomes. It has a strategic geographical and economic situation, as it is located in the middle of the GulfCorridor, an area that connects the ports of Veracruz, New Orleans and Miami as well as the Mississippi delta with Europe. Inside was the US battleship Maine exploded the 15 as February as 1898, a fact that meant the pretext for the United Statesintervened in the War of 95, also known as the Necessary War, snatching the victory from the Mambisa hosts and starting the Spanish-Cuban-American war, which constituted the first conflagration of an imperialist type.
According to ACT Test Centers, the port of Havana is considered one of the most important in the region and during colonial times one of the strategic centers for colonial Spain, which is why the bay was protected with a very important network of fortifications, which include the Torreón of San Lázaro, the Castle of the Three Kings of Morro, the Fortress of San Carlos de la Cabaña, the Castle of Atarés, La Chorrera and other elements dedicated to the protection of the port and the city.

One of the distinctive elements associated with the bay is the lighthouse located in the El Morro fortress, whose construction dates from the 18th century, and which currently works with French optics, which were installed at the time of its construction, including the mechanisms original counterweight and levers for its operation, being the lighting system (currently electric), the only significant change made to this work.
Today one of the fundamental challenges of the bay is to overcome its high levels of pollution that make it one of the most polluted bays in the world, not only due to the high concentration of population on its coastline (close to a million people) but also Most of the city’s industries are located in the bay area, so most of its waste ends up at sea.
Despite everything, the government and several Cuban and international scientific institutions have promoted a great rescue plan for the bay, which seeks through educational formulas to instill values of respect for the environment.
