  • Diocese of Bayombong 
    (Dioecesis Bayombongensis)

  • Suffragan of Tuguegarao
    Created Prelature: Nov. 7, 1966
    Elevated to Diocese: Nov. 15, 1982 by Pope John Paul II
    Comprises the civil provinces of Nueva Vizcaya and Quirino
    Principal Patron: St. Dominic de Guzman, first Sunday of August
    Secondary Patron: St. Vincent Ferrer, April 5

    The first Christian mission established in Nueva Vizcaya was that of Ituy in 1609. This sitio or barrio could have been anywhere between what is now the province of Cagayan in the north, and the mountains bordering Nueva Ecija in the south, because as the Spaniards colonized the Philippines, the entire Cagayan Valley, now Region III, was simply one province called Cagayan.

    The faith spread over the region through the efforts of the Augustinian and Dominican missionaries who came from areas now called Cagayan and Pangasinan.

    By 1717, Father Alejandro Cacho went on mission trips to Ituy, and slowly picked up once again whatever threads of Christianity had been left by the earlier missionaries. Within twenty years, with the help of the Augustinians, Father Cacho was able to baptize many Isinays and Ilongots, original inhabitants of the place, and build cogon chapels in some eight settlements in the Marang Valley.

    Over the years the settlements grew in number. Bujay, now the town of Aritao, and Dupax already had their resident priests. In 1739, Holy Mass was celebrated in Bayombong for the first time. The parishes of Bayombong, Bagbag and Dupax were established in 1741, and that of Solano soon after.

    In April of 1841 the province of Nueva Vizcaya was born, created as a politico-military province by royal decree from Spain. The original line dividing the valley into two — Cagayan and Nueva Ecija provinces — ran between Tumauini and Ilagan (now the capital of Isabela). The name Nueva Vizcaya came from that of a province in Spain called Vizcaya. The capital was the town of Camarag (now Echague in Isabela).

    In 1856, the province of Isabela was created, deriving half of its land from Cagayan, and half from Nueva Vizcaya. With this new partition, Bayombong became the new capital of Nueva Vizcaya.

    On Nov. 7, 1966, the Prelature of Bayombong was established. In 1972 Quirino was made a separate province. The prelature then comprised the civil provinces of Nueva Vizcaya and Quirino.

    On Nov. 18, 1966, Monsignor Alberto Van Overbeke, CICM, was appointed prelate and installed as such. In 1969 he was appointed Bishop-Prelate Ordinary, and ordained bishop in the same year. On Nov. 15, 1982, the prelature was elevated to a diocese, with Bishop Van Overbeke in charge. Because of ill health he asked for assistance and was given a coadjutor-bishop with the right of succession, in the person of Monsignor Ramon Villena. In 1987 Bishop Van Overbeke died and Bishop Ramon Villena became his successor.
