Fort Matías
Punta Guarico was a fort located on the eastern point of the island of Cuba, in the Caribbean. It was controlled by the Spanish Navy until it was disarmed and overrun by the pirate and Assassin Edward Kenway during the Golden Age of Piracy.
After learning of a large sum of gold being held at the fort, Kenway sailed to the stronghold, using the weapons on his ship, the Jackdaw, to destroy the fort's cannons and mortar towers. After doing so, he infiltrated the compound, killing its commanding officer in the process, and barged into the war room, where he found Templar Grand Master Laureano de Torres y Ayala with the gold. Torres told Kenway that the money was to be used to buy the missing Sage Bartholomew Roberts from a slaver named Laurens Prins. Kenway then devised a plan to use Torres and the gold to find Roberts, free him, and use him to find the Observatory.
After the fort was liberated from Spanish control, a harbormaster's post was built at the docks, where Edward was later able to accept two naval contracts from Dutch trader Milo van der Graaff.
