In the Parque Historico Militar, the Castillo de los Tres Reyes del Morro, popularly known as El Morro, stands proudly at the entrance to the Bay of Havana.

El Morro was constructed in the late 16th and early 17th centuries to protect the city against pirate raids. It was designed by Italian engineer Giovanni Battista Antonelli and retains its 17th-century appearance.

The lighthouse is one of the most noticeable changes to the fort. It was renovated multiple times before being replaced with a new solid stone lighthouse in the middle of the nineteenth century. The fort is open to tourists now, and the original lamp still shines.From its higher reaches, you may take in stunning views of the ocean and Havana.
