Francisco Iznaga, a 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 which finally settled in Trinidad where the Torre Iznaga (Iznaga Tower) is. His descendants fought for the independence of Cuba and for annexation to the U.S., from 1820 to 1900.
Trinidad is one of the best-preserved cities in the Caribbean from the time when the sugar trade was the main industry in the region.
