The structure of The Prince castle is that of an irregular pentagon with two bastions, big moats, mining galleries, and a capacity to house over a thousand soldiers. When the jailhouse that had been near the castle of La Punta since 1839 closed down, its functions were taken up by The Prince castle, today still being the city jail.

At the western extremity of the Malecón there is the Torreón de Santa Dorotea de la Luna de La Chorrera. This watchtower was built in 1643 and protected the mouth of the river Almenares against pirates and foreign invaders. This small two-story tower housed artillery, storage rooms and a military of more than 100 soldiers. The tower was designed by the Italian engineer Juan Bautista Antonelli, who also designed El Morro castle. In 1762 this watchtower was taken by the British. Today it houses a small restaurant, Mesón La Chorrera.
Address: Malecón, between Calle 18 and 20. Vedado

 

Tower of  San Lázaro, a small watchtower made by the Spanish in the eighteenth century, is situated near the Malecón.
Like the Torreón de La Chorrera, San Lázaro was one of the first defenses to fall into the hands of the British during the siege of 1762.
The watchtower was constructed next to a creek. In order to build the monument to Antonio Maceo, in 1916, part of the creek had to be filled, leaving the watchtower now a little farther from the sea.
Address: San Lazaro and Malecón. Havana Center
