The Philippines has five UNESCO World Heritage inscriptions in 11 cities and municipalities around the country. These are the Tubbataha Reef in Cagayancillo, Palawan, Puerto Princesa Subterranean River National Park in Palawan, Rice Terraces of the Philippine Cordilleras (Batad and Bangaan in Banaue, Nagacadan in Kiangan, Hungduan and Mayoyao all in Ifugao), Historic Center of Vigan in Ilocos Sur, and the Baroque Churches of the Philippines (Paoay Church in Ilocos Norte, Sta. Maria Church in Ilocos Sur, San Agustin Church in Intramuros, Manila, and Miag-ao Church in Iloilo).
Here is a documentary called Legacy: Philippine World Heritage Sites narrated by Architect Augusto F. Villalon which gives a good introduction to all these sites. I had to divide it into four parts due to length. Part 1 introduces the UNESCO World Heritage List and talks about Tubbataha Reef.
Part 2 discusses the Puerto Princesa Subterranean River National Park and the Rice Terraces of the Philippine Cordilleras.
Part 3 discusses the Historic Center of Vigan and the Baroque Churches of the Philippines.
Finally, Part 4 talks about conservation challenges that each site is faced with and a conclusion for the whole documentary.
