This magnificent church building - originally Romanesque - was dedicated to the patronage of "Saint-ETIENNE". He was one of the first seven deacons of the original Jerusalem community and, according to the biblical accounts in the "New Testament", was also the first martyr (martyr) of early Christianity. The church commemorates his death on the second day of Christmas, December 26th. As the Acts of the Apostles report: When Stephen expressed his vision of the open heavens "But he, filled with the Holy Spirit, looked up into heaven and saw the glory of God, and Jesus standing at the right hand of God" (Chapter 7, Verse 55), the people were so outraged that they drove him out of the city and stoned him.

Located on the property of Blaignan Castle, the Blaignan castle motte is an intriguing historical site. It marks the location of the first village of Blaignan and a medieval castle. Although its remains are mostly invisible today, buried under a grove, the mound reveals an artificial profile characteristic of medieval constructions. Legends speak of a tunnel once connecting the fortress to Isle Abbey, adding a mysterious touch to this place steeped in history.

Before 1876, La Tour de By was called La Roque de By. The vine has been cultivated there for several centuries. Pierre Tizon, Lord of the Fief of By was the owner in 1599. The Château remained in the family until 1725, when it fell to the Comte de Gramont, then to Monsieur de Lignac and, in 1860, to Monsieur Alfred Rubichon who built the current Château La Tour de By in 1876, which overlooks the Gironde. It was then bought by Mr. Julien Damoy who died there in 1942.
