The blast echoes across the water toward the lights of Old Havana, a ritual that has continued since colonial times, when the shot signaled the closing of the city gates. The fortress behind that cannon -- the Castillo de los Tres Reyes del Morro, known simply as El Morro -- has stood on this headland since 1589, designed by Italian military engineer Battista Antonelli to guard the narrow channel where treasure-laden Spanish galleons entered the richest port in the Caribbean. In Spanish, morro means a rock visible from the sea that serves as a navigational landmark, and for more than four centuries, this castle on its cliff has been exactly that: the first and last thing sailors see when entering or leaving Havana.
