The Open Site is the location of a prehistoric village. In 2003, it was bulldozed by the administration of mayor Vicente Y. Emano, despite protests by the Heritage Conservation Advocates (HCA) and other groups. In response to this violation, six HCA members filed an administrative case against the city hall and the contractor. HCA also sent a letter and a large photo to President Gloria Macapagal-Arroyo.
