El Castillo de la Imaculata Concepcion, located on the San Juan river of Nicaragua, was built in the 1670's to protect Lake Nicaragua and its ports, mainly Granada and Leon. Construction began shortly after an attempt was made by the pirate Gallardito to take control of the port of Granada and all the profits gained by its trade industry.
