Trinidad (Spanish pronunciation: [tɾiniˈðað]) is a town in the Sancti Spíritus province of central Cuba. It was granted UNESCO World Heritage Site status in 1988 due to its significance as a center of the sugar trade during the 18th and 19th centuries. Trinidad is considered one of the best-preserved cities in the Caribbean from the time when the sugar industry was the primary source of revenue. It was founded by Diego Velázquez de Cuéllar on December 23, 1514 and named Villa de la Santísima Trinidad.
