Calvario Hill is located in San Francisco, Iriga City in Camarines Sur Province. Calvario Hill is the site of Bicol‘s magnificent Emerald Grotto of our Lady of Lourdes. The Hill has been touted as being the habitat of the Asuang (witch), which is why the hill has been referred to as the “orno” or “oven”. As the result of the angelization of the area the hill became the site for staging “Pagtanggal”, the Iriga folk version of the re-enactment of the Passion of Christ, hence, the name “Calvario Hill”. The first “ermita” or mission chapel of Iriga during Spanish times was erected here as evidenced by religious artifacts unearthened in the site. Opposite the Ermita the Casino Espanol was erected, a favorite converging are for Spanish rulers. When the Americans came at the turn of the century, this was converted into a base for its cavalry forces. During the Japanese occupation, a Japanese garrison was established on the hilltop, utilized as watchtower against guerillas. Many Filipinos met martyrdom in this area.
