Isla Tesoro Fort was a fort located on the edge of the Village Mare on Isla Tesoro. The fortress, manned by Spanish soldiers, was situated near the house of Magistrate Carlos and overlooked the sea.
The fortress was assaulted by a group of pirates, including Captain Hector Barbossa of the Wicked Wench. These pirates eventually managed to raid the armory where, in their inebriated state, they toyed with the numerous weapons and dangerous implements kept there.
A number of pirates were held in the prison of Isla Tesoro Fort and tried to convince a confused dog to approach and surrender the keys it held in its mouth.
