The city started as the small port town of Cavite Puerto that prospered during the early Spanish colonial period when it became the main seaport of Manila hosting the Manila-Acapulco galleon trade and the port used for other heavy and larger sea-bound ships. Thereafter, San Roque and La Caridad, two former independent towns of Cavite province, were later added to form one municipality. The present larger Cavite City now includes the communities of San Antonio (includes Cañacao and Sangley Point), the southern districts of Santa Cruz and Dalahican, and the outlying islands of the province, including the historic Corregidor Island.
