You might have seen this stronghold above the bay entrance at Santiago bay in my last post on the island Granma. Here you can find out a bit more.
This old spanish castle was built, to defend the citizens against pirate attacks, back in the 17th and 18th century. Nowadays you can visit the castle. You can walk around and visit many of the rooms from the top down to the storage rooms, the jail and the chapel.
Every evening right after sunset (appr. 6 p.m.) a group of soldiers, dressed up like the soldiers back in the 18th century, fire a cannon as a salut. You can watch that from a balcony above. This day, the group was commanded by a capitana, a female captain.
Next stop: Santiago de Cuba!
