Pila and adjacent towns along the shores of Laguna de Bay are considered by archaeologists as one of the oldest settlements in the Philippines. The community is one of three such concentrations of population known archaeologically to have been in place before A.D. 1000. Archaeologists recovered in Pinagbayanan potteries and artifacts that indicate considerable settlement in the area during the Late Tang Dynasty (900 A.D.). Archaeologists also recovered ancient horse bones ending the debate on whether the Spaniards brought them or not. The scientists were able to uncover Philippines’ oldest crematorium in the same area. It is worthwhile to note that the oldest Philippine document, the 900 A.D. Laguna Copperplate Inscription, mentioned Pila (as "Pailah") twice and its ruler Jayadewa.
