San Dionisio, officially the Municipality of San Dionisio (Hiligaynon : Banwa sang San Dionisio, Tagalog : Bayan ng San Dionisio), is a municipality in the province of Iloilo, Philippines. According to the 2020 census, it has a population of 39,048 people. [5]
During the Spanish Colonization of Philippines, a native leader named "Dionisio" had cleared the forest land to create a settlement called "Lakdayan". In 1877 Spanish arrived and renamed "Lakdayan" to "Dionisio" in the honor of humble fisherman founder of the settlement. Spanish converted the natives and appointed St. Vincent Ferrer as Patron Saint of the settlement. Spanish set up the municipality at Concepcion, of which Dioniso was a part of. During Spanish times, the head of the local government of Concepcion was titled "Kapitan" (captain) and the subordinate leaders in San Dionisio were titled "Tenientes" (lieutenant) and hereditary Cabeza de Barangay (head of barangay). Eventually Sara was carved out of Concepcion to establish an eponymous municipality, which also included Dionisio as one of the constituent barangay of Sara. In 1920, San Dionisio municipality was established after carving it out of Sara municipality.
San Dionisio is 106 kilometres (66 mi) north of Iloilo City and 91 kilometres (57 mi) east of Roxas City. The Quiniluban Island, Tago Island and Igbon Island, extinct valconic islands known for coral reef scuba diving and beach ecotourism, lie in the east across the Concepcion Bay. The Mount Opaw, with the clear views of ocean and islands, is the tallest range with gentle slope with a single peak with trails in several directions to ascent.
San Dionisio is politically subdivided into 29 barangays. [6] Each barangay consists of puroks and some have sitios.
