Intramuros, often referred to as the "Walled City," is a historic district in Manila, Philippines. Built during the Spanish colonial period in the late 16th century, it served as the political and military base of Spanish rule. The area is enclosed by thick defensive walls and moats, covering around 64 hectares. Key landmarks within Intramuros include Fort Santiago, Manila Cathedral, and San Agustin Church. Despite significant destruction during World War II, Intramuros has been partially restored and remains a symbol of the city's colonial past.
