Barangay Pilar, known as “Sitio Camansi” and previously a part of Barangay Paradise. Barangay Pilar is sited along the way from Imelda to Bayog at a low land area in Zamboanga del Sur under the Municipality of Siay. People of Sitio Camansi cultivated the area and planned to detach from Paradise and stand as another barangay.
