Although ancient authors claimed that Ramiro was a participant in the First Crusade, such participation is highly unlikely. He had supposedly left together with other nobles on March 15, 1095, but that is impossible as the crusade had not yet been called at the council of Clermont and this did not occur until a few months later. On the other hand, according to Antonio Ubieto Arteta, it was to be supposed that had he gone to the Holy Land, "he would have remained in the Christian army until the conquest of Jerusalem; however, we find him in Valencia around 1098, marrying a daughter of El Cid and in July 1099 accompanying the body of El Cid to Cardeña". He initiated the construction of Santa María de La Piscina, which was consecrated in 1137.
