English: Intramuros (Latin, "within the walls") is the oldest district and historic core of Manila, the capital of the Philippines. Also called the Walled City, it was the original city of Manila and was the seat of government when the Philippines was a component realm of the Spanish Empire. Districts beyond the walls were referred as the extramuros of Manila, meaning "outside the walls".

Construction of the defensive walls was started by Spanish colonial government in the late 16th century to protect the city from foreign invasions. The 0.67-square-kilometre (0.26 sq mi) walled city was originally located along the shores of the Manila Bay, south of the entrance to Pasig River. Guarding the old city is Fort Santiago, its citadel located at the mouth of the river. Land reclamations during the early 20th-century subsequently obscured the walls and fort from the bay.

Intramuros was heavily damaged during the battle to recapture the city from the Japanese Imperial Army during the Second World War. Reconstruction of the walls was started in 1951 when Intramuros was declared a National Historical Monument, which is continued to this day by the Intramuros Administration (IA) [Wikipedia.org]
