About St Alban
According to Bede's Ecclesiastical History of the English People, Alban was a pagan living at Verulamium (now St Albans), who converted to Christianity, and was executed by decapitation on a hill above the Roman settlement of Verulamium. St Albans Abbey was later founded near this site. The date of the execution is best left to the venerable Bede: "when the cruel Emperors first published their edicts against the Christians”.
Alban sheltered a Christian priest in his home, and was converted and baptised by him. When the "impious prince", as Bede has called him, sent Roman soldiers to Alban's house to look for the priest, Alban exchanged cloaks with the priest and was arrested in his stead at Chantry Island.
Alban was taken before the magistrate, who was furious at the deception and ordered that Alban be given the punishment due to the priest if he had indeed become a Christian. Alban declared, "I worship and adore the true and living God who created all things." These words are still used in prayer at St Albans Abbey. St Alban was eventually sacrificed to the Roman gods and was condemned to death. He was taken out of the town across the River Ver to the top of the hill opposite. The reputed place of his beheading is where St Albans Cathedral now stands.
