Located in the province of Sancti Spíritus, in Central Cuba, is the perfectly preserved Spanish outpost of Trinidad, famous for its colonial old town and cobblestone streets. It was founded in the early 16th century in honor of the Holy Trinity and was a bridgehead for the conquest of the American continent. Its neo-baroque main square, Plaza Mayor, with its 18th- and 19th-century buildings, such as the Palacio Brunet and the Palacio Cantero, were built in its days of prosperity from the sugar trade. Iglesia de la Santísima is a 19th-century cathedral with a vaulted ceiling and carved altars.
Trinidad de Cuba, together with the nearby Valle de los Ingenios has been a Unesco world Heritage site since 1988.
