The walled city of Intramuros will take you back in time to the Spanish conquest of Manila in the late 16th century. See the Fort Santiago Citadel itself and the treasures within, like the Spanish Colonial San Agustin Church and Bahay Tsinoy Museum, which is dedicated to the Philippines' Chinese immigrant community.
Manila isn't just about the past. The vibrant Makati district is pulsating and futuristic. Its tree-lined boulevards are home to modern architectural landmarks like the Ayala Museum and contemporary shopping malls, like Glorietta and the Greenbelt, which are marvels of architecture (and air conditioning) in their own right.
