<P> The Spanish influence in Bicol resulted mainly from the efforts of Augustinian and Franciscan Spanish missionaries . The first churches in Bicol, the San Francisco Church, and the Naga Cathedral, both in Naga, along with the Holy Cross Parish in Nabua, Camarines Sur, are instituted by the Holy Order of the Franciscans . One of the oldest dioceses in the Philippines, the Archdiocese of Caceres, was also instituted in the Bicol Region . During this time, Bicol was dotted by many astilleros (shipyards) which were focused on constructing Manila Galleons from the local hardwood forests . </P> <P> The region comprises six provinces: Albay, Camarines Norte, Camarines Sur, Sorsogon and the island - provinces of Catanduanes and Masbate . </P> <P> As of 2015, Camarines Sur is the region's largest province in area and population, occupying 5,481.6 km (2,116.5 sq mi) or around 30.4% of the total land area with a population of 1,952,544 .
