The Angono Petroglyphs are petroglyphs carved into a rock wall in Angono, Rizal, Philippines. It consists of 127 human and animal figures engraved on the rockwall probably carved during the late Neolithic, or before 2000 BC. They are the oldest known work of art in the Philippines. These inscriptions clearly show stylized human figures, frogs and lizards, along with other designs that may have depicted other interesting figures but erosion may have caused it to become indistinguishable. The engravings are mostly symbolic representations and are associated with healing and sympathetic magic. The site is sacred for indigenous Tagalog folk religion and is believed to be a home for "anitos."
