[2] After the ceremony, officiated by the Archbishop of Tarragona, the bridegroom again transmitted to his father his desire to renounce his rights to the throne and enter a convent.

After the wedding ceremony, and after a discussion with his father, he fled on horseback, leaving his wife abandoned, and in December 1319, renounced his rights to the throne of Aragon in the Convent of San Francisco of Tarragona.

[3] After her stay in Tortosa, Eleanor lived in the cities of Zaragoza, Calatayud and Ateca, from where some Castilian ricohombres returned her to the Kingdom of Castile and León.

[6] In Ágreda in January 1329 the betrothal between Eleanor and King Alfonso IV of Aragon was signed, and the wedding ceremony took place one month later, on 5 February in the Church of San Miguel de Tarazona.

The Kingdom of Aragon had breached several marriage agreements, returning to Castile several princesses after breaking off engagements, and this union put an end to the practice.

Eleanor became a disruptive influence in Aragon, plotting to advance the interests of her own sons over those of her stepson, Peter, born from Alfonso IV's first marriage with Teresa d'Entença, Countess of Urgell, who died in 1327.

Alfonso IV was generous and on 28 December 1329, he granted Ferdinand the Marquisate of Tortosa and the cities of Albarracín, Orihuela, Callosa, Guardamar, Alicante, Monforte, Elda, La Mola, Novelda and Aspe.

These donations made by Alfonso IV diminished the territorial patrimony of the crown and mainly affected Peter, producing a climate of resentment in the Aragonese court.

[9] At first, the new monarch moved to confiscate Eleanor's revenues and prosecute her protector Pedro de Ejérica, but in 1338 he confirmed her and her sons in possession of their domains, not wishing to antagonise Castile at a time when the whole Iberian Peninsula was threatened by a new Moorish invasion.

It has been assumed that Queen Eleanor was buried in the tombstone of María of Almenara, whose mortal remains could be transferred to another tomb placed in the same nave, and inside which a female mummy, corpulent and of mature age.

In the Church of Nuestra Señora del Manzano of Castrojeriz a tomb is conserved, attributed to the Queen Eleanor de Castile,[16] that is located at the feet of the church, near the baptistery,[17] and was discovered in June 1970, hidden behind a wall of adobe, by the Rescue Mission Group Marqués de Camarasa School Group.

[18] From the moment of his discovery, the grave was attributed by the experts to Eleanor, daughter of Ferdinand IV, because the fashion of the sepulcher corresponds with other tombs realized in the middle of the 14th century, as well as by the fact that on its cap appears the sculpted figure of a woman.
