Angono Petroglyphs

I helped my daughter did her research this weekend about Rizal Province specifically regarding food, crafts, crops and arts. We encountered this so-called "Angono Petroglyphs" which was discovered by our National Artist Carlos "Botong" Francisco in 1965. The said rock art is believed to be around in 3000 BC making it the most ancient prehistoric art work in our country. There are rock engravings of human and animal figures which made it to be part of World Inventory of Rock Art.
