Born and raised in Tours, France, Bertha was raised a Christian. Her marriage to King Æthelberht of Kent, an English pagan, was conditional on her being permitted to continue to practice her faith.
Following her move to Canterbury, Kent, Bertha began work to restore a Christian church in the city. There had been a church in Canterbury during the Roman occupation of Britain, but it had been destroyed during the Saxon invasions and was in a state of ruin by the time Bertha arrived.
Bertha used the restored church as her private chapel and dedicated it to Saint Martin of Tours. St Martins is still standing today, and is the oldest church in the English-speaking world.
In 596 Canterbury was visited by Augustine, Gregorian monk sent by Pope Gregory I to convert the English. Bertha received Augustine warmly and encouraged him to settle in Canterbury, where he went on to found a monastery and became the first Archbishop of Canterbury in 567.
Thanks to Bertha’s early influence, Canterbury remains the seat of the Church of England.
King Æthelberht eventually converted to Christianity himself, and the couple had two children, Eabald and Æthelburg.
Bertha was canonised as a saint; her feast day is on 1st May.
