Canonry of the Cathedral of Tarragona

Oleguer, bishop of Barcelona from 1116 to 1137, is believed to have been born around 1060 and was the son of a high official of Ramon Berenguer I. He received a thorough education and, in 1076, joined the chapter of canons at the cathedral. In 1089, he was ordained as a deacon. Bishop Bertran ordained him as a priest, and by 1093, he was already a member of the community of canons of Saint Ruf, which the same bishop had founded in Sant Adrià. The following year, Olegarius became the prior of Sant Adrià, a position he left to become a member of the canonry of Saint Ruf in Avignon, where he took on the role of abbot.

In 1115, he accompanied Douce of Provence to Barcelona for her marriage to Ramon Berenguer III. At that time, Oleguer was acclaimed as bishop of Barcelona, a position he initially refused. After papal intervention, he accepted and also assumed the role of restorer of the archbishopric of Tarragona (1119), a role he held without relinquishing his position as bishop of Barcelona. He remained highly active, participating in councils, political matters of the time, and traveling to the Holy Land. He died in 1137 and is venerated as a saint by the Church. His tomb is located in the cathedral of Barcelona.
