Here are three cards from the Philippines, all of different UNESCO sites:
The Church of San Agustin in Manila is one of the Baroque Churches of the Philippines. I already have a card of the church in Miag-ao, so now I have half of the churches that are part of this UNESCO site.
This card shows the houses in Vigan. Vigan was a port city founded by the Spanish around the 16th century, but it was used as a coastal trading post by native peoples long before that. It was preserved because it is the finest examples of Spanish colonial architecture.
Finally, the Puerto Princesa subterranean river. This national park was declared a UNESCO site in 1999. The river winds through underground caves for 8 km; the cave is about 24 km long. The cave was also listed as one of the New 7 Wonders of Nature in 2012.
The card of Puerto Princesa came from Jan; the other two cards came from ‘lypz’ — both from the Postcrossing forum. Thanks!
