The Port of Cavite "(Puerto de Cavite)" was linked to the history of world trade. Spanish galleons sailed every July to Acapulco (Mexico) while another ship sailed from Acapulco to Cavite. Galleons and other heavy ocean-going ships were not able to enter the Port of Manila along Pasig River because of a sand bar that limits entrance to the river port only to light ships. For this reason, the Port of Cavite was regarded as the Port of Manila, the main seaport of the capital city.
