History
Established in 1578, Agoo is considered the oldest town in La Union and was formerly part of Pangasinan. The town's name is believed to have come from the pine-like "aroo" trees that once lined its riverbanks.
Agoo played a significant role in early evangelization efforts in Northern Luzon, with Franciscan missionaries founding a church dedicated to St. Francis of Assisi. Over time, other religious orders such as the Augustinians contributed to the community's development by introducing education, religious practices, and construction techniques.
One notable religious structure is the church that was later elevated to the status of Basilica Minore of Our Lady of Charity in 1981. Agoo also witnessed conflict during the Japanese occupation in World War II, including tragic events in Barangay Macalva. In the postwar years, the town experienced continued growth and infrastructure development, supported by various civic leaders who helped promote its cultural and historical significance.
