A perfect view of Old Havana is gleaned from Castillo del Morro. The “Morro” as it is known locally is a picturesque fortress protecting the entrance to Havana bay. The structure of the castle Los Tres Reyes del Morro is built in such a way de to the step along the harbor mount in Havana. Commissioned by the king of Spain the big stone slabs used were known locally as El Morro stone, from which the name was derived. Military man Juan de Texeda was sent by the king of Spain accompanied by the military engineer Battista Antonelli, both arrived in Havana in 1587 and began the task of building the Castillo del Morro.
