Manila, the capital of the Philippines, is a densely populated city. It is located on a bay on the island of Luzon. Here, Spanish colonial architecture mixes with modern high-rises. Intramuros, a walled neighborhood from the colonial era, forms the core of the old city. There you will find the 16th century baroque church of San Agustin and the Fuerza de Santiago, an old fortification and former military prison.
