Trinidad is a town in the province of Sancti Spíritus, central Cuba. Together with the nearby Valle de los Ingenios, it has been one of UNESCOs World Heritage sites since 1988.Trinidad was founded on December 23, 1514 by Diego Velázquez de Cuéllar under the name Villa De la Santísima Trinidad. Francisco Iznaga, a rich Basque landowner in the southern portion of Cuba during the first 30 years of the colonization of Cuba, was elected Mayor of Bayamo in 1540. Iznaga was the originator of a powerful lineage that finally settled in Trinidad where the Torre Iznaga is. His descendents fought for the Independence of Cuba and the Annexation to the US from 1820 to 1900. It is one of the best preserved cities in the Caribbean from the time when the sugar trade was the main industry in the region.
