Ilocos Sur

Ilocos Sur links to 2662 places across 20 topics through 120 Bunkabop connections, spanning Spanish colonial religion, revolutionary history, and modern Philippine politics. The province shares its strongest overlaps with the Philippines, Manila, and the United States, reflecting both Augustinian missionary roots and later diaspora reach. Military threads run deep, from the 1899 Battle of Tirad Pass near Cervantes to the Japanese Imperial landing at Vigan in December 1941. Birthplace of writer Eileen Tabios and actress Alma Moreno, the region also anchors UNESCO World Heritage recognition.
