The Fort Santiago is one of the oldest forts and historic sites in Manila. It was heavily fortified and used as a defence fortress during the Spanish Colonial period. Originally built in 1571, a year after Manila became the capital of the Philippines, Fort Santiago was only a structure of palm logs and earth until it was destroyed during an attack by Chinese Pirates. The fort was then rebuilt and was made of thick and high stonewalls. A moat was also used to stop invaders from accessing the fort. This lasted until the Battle of Manila in 1945. Entrance fee for adults is Php 75 and P40 for students and children.
