The province of Ilocos Sur is where the Ilocos Region’s myriad of cultures and histories converge to become a living museum of a spirited past. A national shrine, a national landmark, a national museum, heritage museums, ancestral houses, period houses, cobble-stoned streets – they all share space in the timeless land of Ilocos Sur.

Found in the province is the historic town of Vigan, which was inscribed in UNESCO’s World Heritage List in November 1999. Established in the 16th century, Vigan is the best preserved example of a planned Spanish colonial town in Asia.

Ilocos Sur has 34 municipalities which are subdivided into 764 barangays. They are Alilem, Banayoyo, Bantay, Burgos, Cabugao, Candon, Caoayan, Cervantes, Galimuyod, Gregorio del Pilar, Lidlidda, Magsingal, Nagbukel, Narvacan, Quirino, Salcedo, San Emilio, San Esteban, San Ildefonso, San Juan, San Vicente, Santa, Santiago, Sta. Catalina, Sta. Cruz, Sta. Lucia, Sta. Maria, Sto. Domingo, Sigay, Sinait, Sugpon, Suyo, Tagudin, and Vigan.
