History

In 1823, The catholic faith of the province was made atop a hill near the Abra River. Where a Augustinian priest by the name of Fr. Bernardo Lago arrived on the town of Pigidian, he built a church and a rectory atop the hill. [3]

In the year of 2022, The Abra Fault made a major magnitude 7.0 earthquake, in Abra.[4]

Geography

The Abra originates in the southern section of Mount Data. It descends westward to Cervantes, Ilocos Sur, and flows into Abra. At a point near the municipality of Dolores, it is joined by the Tineg River, which originates in the uplands of Abra.[5] There are also other small rivers like the Binongan River, Ikmin River, and other rivers connecting to Abra River.
