Twelve kilometers northwest of Trinidad, the Manaca-Iznaga Tower continues to watch over the Valle de los Ingenios (Valley of the Sugar Mills) as it did over 180 years, although its purpose today has nothing to do with its origin.
The tower is divided into seven levels of different geometrical shapes that go from squares to octagons, has spacious arches and a 184-step internal staircase from the base to the top. It is built with mud bricks and a traditional mortar of lime and sand. From its top, the visitor can take in the entire valley, which was declared a UNESCO Cultural Heritage Site thanks to the preservation of 65 archaeological plots. The tower was declared a national Monument in 1978.
