The Church dates back to the 12th century and is named after the 6th century German-born princess Radegonde, or Radegund in English. After being forced into a marriage at the age of 19 with Clotaire the Frankish King, who also organized her brother’s murder, Radegund, daughter of the King of Thuringen entered holy orders in Poitiers. It is here that she founded the Sainte-Croix abbey where she devoted herself to prayers and a life of good deeds. She became recognized as the one to have killed with the sign of the cross the ‘Grand’Goule’, the monster that haunted Poitier’s underground passages. She died in Poitiers in 587.
Claude Monet was buried in the cemetery surrounding the church on 8th December 1926.
As it was heavily damaged during the liberation of Giverny in 1944, the Church underwent vast restoration work between 2008 and 2010.
