Angono Petroglyphs, the oldest work of art in the Philippines, are cave carvings found in the province of Rizal dated 3000 B.C. It was in 1965 when these cave carvings were discovered by National Artist Carlos “Botong” Francisco when he lead a troop of boy scouts in the mountainside of Angono and Binangonan. The site is actually on the political jurisdiction of Binangonan. But it was named after Angono, a municipality 3.5 kilometers away, since it was Francisco’s hometown. To date, to recognize the two municipalities, the landmark is now officially known as the Angono-Binangonan Petroglyphs Site.
