Fort San Felipe (Spanish: La Fortaleza de San Felipe; Filipino: Moog ng San Felipe Neri) is a military fortress in Cavite City, in the Province of Cavite, Philippines. It was constructed by the Spanish military in 1609 in the first port town of Cavite, the historic core of the present and larger Cavite City, for its protection. Less than half of the original historic structure survives today. The remaining structure is made of granite blocks with 30-foot high walls and features a wide stairway leading to the top of the bastions and remaining walls. Naval memorabilia including antique cannons and cannonballs decorate the lawns of the fortification. Fort San Felipe is located within the 9-hectare (22-acre) Naval Base Cavite of the Philippine Navy and is not open to the public.
