Ilocos Sur

Ilocos Sur stretches along a narrow coastal plain between the South China Sea and the Cordillera mountain range, covering 12,840 square kilometers of varied terrain.

The province emerged as a distinct administrative region in 1572 when Spanish conquistador Juan de Salcedo established control over the northern territories of Luzon.

The population consists of 66 percent Ilocano speakers who maintain traditional practices through weaving, pottery making, and annual festivals in Vigan City.

Transportation networks connect the municipalities through the Manila North Road, while regular buses operate between major cities and the regional center of San Fernando.

Ilocos Sur houses two UNESCO World Heritage sites: the preserved Spanish colonial town of Vigan and the Baroque Church of Santa Maria.
