The Bicol Region is located in southern Luzon island and is bounded by water on three sides. It was originally called Ibalon and was first mentioned in Spanish documents in the 1500s. The Spanish influence came through Augustinian and Franciscan missionaries who established some of the oldest churches. The region is composed of six provinces and several cities, with Legazpi and Naga being the major urban centers. Bicolanos speak various Bikol languages and celebrate Catholic fiestas. Agriculture, fishing, and coconut farming are important economic activities. Popular foods include Bicol Express, laing, and dishes made with pili nuts.
