The UNESCO (United Nations Educational, Scientific and Cultural Organization) has designated six World Heritage Sites in the Philippines.
The UNESCO World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention.
The Philippines, following its ratification of the convention on Thursday, September 19, 1985, made its historical and natural sites eligible for inclusion on the list.
Of those six sites, three are cultural and three natural.
In 2015, the 28 sites in the 'Tentative List' were revised.
Currently, the Tentative List for possible nomination in the future contains nineteen submissions.
The Philippine National Government, the National Museum of the Philippines, the University of Santo Tomas, the UNESCO Commission of the Philippines and other concerned parties encourage more historic churches, municipal and city governments, provincial governments, national parks, and private entities to submit their nominations of sites that they have jurisdiction of to UNESCO to revitalize heritage conservation in the country and to internationalize the importance of heritage conservation in the Philippines, which is seen to be the greatest frontier of westernized Asian nations in a hastily industrializing Asia.
The brick church follows the standard Philippine layout, with a monumental facade masking a straight roof-line covering a long rectangular building.
It is alleged to be built on a solid raft as a precaution against earthquake damage.The walls are devoid of ornament but have delicately carved side entrances and strong buttresses.The Church of Santo Tomas de Villanueva stands on the highest point of Miagao, its towers serving as lookouts against Muslim raids.The Church of San Agustín at Paoay is the most outstanding example in the Philippines of 'Earthquake Baroque'.Fourteen buttresses are ranged along the lines of a giant volute supporting a smaller one and surmounted by pyramidal finials.A pair of buttresses at the midpoint of each nave wall have stairways for access to the roof.
