Pililla has preserved some religious and non-religious traditions such as the Santa Cruzan or Flores de Mayo, wherein men and women walk all over town with their gowns.

Town Fiesta during the month of July is being visited by people from the city to experience the celebrations especially the amateur shows at night.

The place was divided by the Spaniards into five “rancherias”: In 1583, Pilang Moróng became an independent town, and rechristened Pililla.

In 1599, 16 years after the town was given autonomy, the supreme government granted Pililla the authority to construct a church.

The following towns participated in the said election: Moróng, Pililla, Tanay, Baras, Jalajala, and San Diego.

On July 9, 1885, the government received another petition from the Cabeza de Barangay of San Diego requesting that it be made into a kind of self-governing barrio of Pililla, on account of its remoteness.

On January 25, 1886, the government agreed to make San Diego into a “Visita con Teniente Absolute”, on the condition that the barrio construct the necessary public buildings.

In 1896, the Katipuneros of Pililla and San Diego established their military camp at Rambo or Pabaláng na Gubat.

The towns of Pililla and San Diego were integrated into the newly created province of Rizal in June 1901.

On September 24, 1929, Don Ananías Vicencio, a philanthropist in public documents, donated a tract of land containing approximately 15 hectares to the families of Manuel Roxas, Leoncio Carungay, and Quintin Golliden, all of Jalajala, who shall distribute and assign free of charge and to the best interest of the residents, the said lot at Longos, Barrio Quisao, Municipality of Pililla.

During the liberation of the town on March 18, 1945, nearly 3/4 of all the houses and public buildings were either burned or destroyed by American and Filipino military bombing and shelling.

The PCAU of the US Army reestablished the municipal government of Pililla on April 20, 1945, with the designation of Lucio Aquino, an active guerrilla leader, as mayor.
