Dedication of the Basilicas of Saints Peter and Paul

Dedication of the basilicas of Saints Peter and Paul, Apostles. The first of these was built by the Emperor Constantine over the grave of St. Peter in the Vatican Hill, and due to its deterioration over the years it was rebuilt with more width and again consecrated on this same day of its anniversary. The other, built by the emperors Theodosius and Valentinian in via Ostiense, after getting annihilated by an unfortunate fire was rebuilt in its entirety and dedicated on December 10. Their joint commemoration is meant to signify, somehow, the brotherhood of the Apostles and unity in Church (1626; 1854).
