The construction of the Fort began in the late 16th century by father Nicholas Melo and father Alonso Colosa and lasted over hundreds of years. Only in the early 18th century the Fort was completed under the guidance of his father hipólito Casiano. The fortress was made in the shape of a diamond and occupied an area of 162 sq. m. It was built on the coast on a high promontory, and its walls are composed of a mixture of pebbles and limestone. By analogy with some other Spanish FORTS, inside Fort Cagayancillo is the Church, surrounded by massive walls with a height of 12 meters and 3 meters thick. These walls protect the inhabitants of the Fort from attacks of pirates.
