Puerto Cabello
At the time of the castle's construction, Puerto Cabello was a trading centre of the Guipuzcoan Company of Caracas. The castle was intended to protect the settlement and its important harbour from piracy and conflicts with rival colonial powers. The castle resisted an attack from the Royal Navy in the Battle of Puerto Cabello (1743). Despite this victory over the fleet of commodore Charles Knowles, the Spanish continued to strengthen the fortifications of Puerto Cabello and built another fort, Solano Castle, above the town.
