About Ilocos Norte
Sitting in the Northwestern part of the Philippines, Ilocos Norte is named the Northern Gateway of the Philippines. This province is sometimes called the Marcos Country because it was from here that former President Ferdinand E. Marcos and the other Marcoses involved in politics have come from. Other than the Marcoses, people from Ilocos Norte are painter and activist Juan Luna, Girl Scouts of the Philippines founder Josefa Llanes-Escoda, the second Filipino chairperson of the University of the Philippines, Tomas Fonacier and actor Jake Cuenca.
Dragon Fruits, called “Saniata” by locals, is famous in this province. Delicacies from Ilocos Norte are the traditional Empanadas of Batac city, crunchy and puffy Chicacorn and Dudol, a thick, coconut-flavored dessert featured in the Guling-Guling Festival.
Ilocos Norte and Ilocos Sur were one until a period in which the Spaniards were making much effort to gain more political control. This became a challenge with the increasing population in Ilocos, so by a Royal Decree in 1818, Ilocos was split into two provinces.
