@94576702 In the 1697 raid on Cartagena, during the War of the Grand Alliance, the castle fell to the French privateer Baron de Pointis.
British Admiral Edward Vernon attacked the fortress in the 1741 Battle of Cartagena de Indias, during the War of Jenkins' Ear. Vernon's forces were repelled by the Spanish admiral Blas de Lezo. 
During the Spanish American wars of independence by 1815 a large Spanish expeditionary force under Pablo Morillo had arrived in New Granada. Cartagena fell in December.

Thank you dear for the history lesson.

We may say: Except in 1741, the castle wasn't that effective. 

 @94576702 well, I would like to believe that its presence probably prevent more attacks.
