After the war, Bacnotan became the provisional seat of the provincial government, since San Fernando was then in ruins. As a consequence of this transfer, the La Union National High School was also moved to Bacnotan. When things went back to normal, the provincial government was again moved to San Fernando and the La Union National High School followed afterward. The transfer of the provincial high school in Bacnotan resulted in the establishment of the North Provincial High School (now Bacnotan National High School.)
