The Vitoria Diocesan Historical Archive is hosting an exhibition titled El Domund al descubierto

The exhibition features historical records of the Misiones Diocesanas Vascas, which began in 1948 when eight diocesan priests from Vitoria were sent to Los Ríos, Ecuador. Vanessa Jiménez and Itziar Lafuente, technicians at the Vitoria Diocesan Historical Archive, manage the collection. Jiménez noted that the movement started following a speech by Ángel Sagarmínaga, the first director of Obras Misionales Pontificias España, which encouraged the Vitoria seminary to establish the missions.

These missions were distinct because the priests remained part of the diocese, which sent, supported, and managed them both abroad and upon their return. While this model faced initial difficulties, it resulted in the sending of 750 priests, including 200 during the 1960s.

Following the creation of the dioceses of Bilbao and San Sebastián in 1950, the Misiones Diocesanas Vascas served as a coordinating body for missionary needs, even though individual priests reported to their respective bishops. The organization continued to function in this capacity until its dissolution in 2020.
