Ilocos Sur is a province of the Philippines located in the Ilocos Region in Luzon. Its capital is Vigan City and borders Ilocos Norte and Abra to the north, Mountain Province to the east, and La Union and Benguet to the south. To the west of Ilocos Sur is the South China Sea.

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. Found in the province is the historic city 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. Its architecture reflects the coming together of cultural elements from elsewhere in the Philippines and from China with those from Europe to create a unique culture and townscape without parallel anywhere in East and Southeast Asia. Its Kamestizoan District is replete with ancestral houses with ancient tiled roofs, massive hardwood floorings, ballustrades and azoteas in varying Spanish-Mexican-Chinese architectural styles.
Centuries-old Sta. Maria Church, declared a National Landmark, was used as a fortress during the Philippine Revolution of 1896. Tirad Pass, declared a National Shrine, had been the last stand of the Filipino Revolutionary Forces under General Emilio Aguinaldo during the same period. Bessang Pass served as the backdoor to General Yamashita’s last ditch defense during the last stage of World War II.
