Intramuros (lit. within the walls) is the historic centre and oldest district Manila, Philippines. It is also called the Ciudad Murada (Walled City) because of its most famous feature: a nearly three-mile-long circuit of massive stone walls and fortifications that almost completely surrounds the entire district. At the time of the Spanish Colonial Period, it was synonymous to the city of Manila itself. It 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 (lit. outside the walls) of Manila.
