The Cathedral of the Saviour is a Catholic church in Ávila in the south of Old Castile, Spain. It was built in the late Romanesque and Gothic architectural traditions.
It was planned as a cathedral-fortress, its apse being one of the turrets of the city walls. It is surrounded by a number of houses or palaces, the most important being: the Palace of the Evening, the Palace of the Infant King, and the Palace of Valderrábanos, which were responsible for the defence of the Puerta de los Leales also known as La Puerta del Peso de la Harina .
Saint Secundus or Secundius is venerated as a Christian missionary and martyr of the 1st century, during the Apostolic Age. He evangelized the town of Abula, which has been identified as either Abla or Ávila, and became its first bishop.
The ancient town of Abula is mentioned by Ptolemy in his Geographia as located in the Iberian region of Bastetania. It is said to be one of the first cities in Hispania that was Christianized, specifically by Secundus. Ávila may have been the ancient Obila and Abula may have been the present town of Abla.Secundus is one of the group of Seven Apostolic Men , Christian clerics ordained in Rome by Saints Peter and Paul and sent to evangelize Spain. Beside Secundius, this group includes Saints Hesychius, Caecilius, Torquatus, Euphrasius, Indaletius, and Ctesiphon.
