The province of Granma limits to the north with the provinces of Las Tunas and Holguín, to the south with the province of Santiago de Cuba and the Caribbean Sea, to the east with the provinces of Holguín and Santiago and to the west with the Gulf of Guacanayabo.

 The origins of the Granma province as such date back a few decades.  It was born when Commander in Chief Fidel Castro Ruz, on November 7, 1976, from the historic La Demajagua sugar mill, before thousands of residents, proclaimed that the former province of Oriente was divided into five provinces: Guantánamo, Santiago de Cuba, Holguín, Las Tunas and Granma.  But the leader of the Revolution found it good to make a pertinent clarification: the East was not divided, but multiplied in those brother territories.

At that time, a new political-administrative division of the country was under way, so the old regions of Bayamo and Manzanillo were integrated into a single territorial community and the city of Bayamo was chosen as the provincial capital, without losing sight of the character of Manzanillo in each of the development plans.  It bore the name of Granma, in homage to the white yacht that brought the liberating expedition from Mexico along the Niquero coast on December 2, 1956. Its name is Granma.

 Due to its size, Granma is the sixth largest province on the island, it is subdivided into 13 municipalities: Bartolomé Masó, Buey Arriba, Campechuela, Cauto Cristo, Guisa, Jiguaní, Manzanillo, Media Luna, Niquero, Pilón, Río Cauto, Yara and Bayamo, provincial capital.

 Its territory covers an area of ​​8,362 square kilometers - it does not include the keys that have an area of ​​9.6 square kilometers -, which constitutes 7.5% of the total area of ​​the country.

 But the origins of the cities and towns of Cauto and Guacanayabo are rooted in a remote past, trapped in ancient myths and legends.  Around two hundred aboriginal archaeological sites have been found in this geography, evidencing the existence of numerous Indo-Cuban communities in different phases of evolution.  In those stadiums are the true origins of Bayamo, Jiguaní, Yara, Vicana, Santa Rita and Guamo, among many more.
