Braud would come from beraud, Saintonge form of the Germanic name berard, old lord" or from the Gascon braou, "bull", a sign that these cattle were raised in the swamps or even from the old French brai, "mud", "swampy place".
The parish of Braud is cited under the name of Sanctus Saturninus (Saint Saturnin) of Braud.
The drying out of the marshes, in the 17th century, on the initiative of the Duke Claude de Saint Simon, governor of Blaye, was to make it possible to transform the marshes into "good nature of arable land" and create villages. The draining finished, the plots are allocated, the smallholdings appear. The number of inhabitants encouraged the Duke of Saint Simon to found two parishes: the parish of Saint Louis (all the part of the large marsh located between the Gironde and the ring canal, between the Clonges canal and that of Fréneau), in l honor of the King of France and that of Saint Simon.
The church, the presbytery and the cemetery built between 1665 and 1667 were destroyed during the Revolution of 1789. Rebuilt in 1895 in a neo-Gothic style and on a new north-south orientation, it is located north of the town of Braud -and-Saint-Louis. The spire of the bell tower culminates at 37 meters in height.
After the Revolution, the parish of Saint Saturnin de Braud and the parish of Saint Louis des Marais were united to form the municipality of Braud and Saint Louis.
THE CROSS OF SAINT LOUIS
A cross found in the attic of the presbytery of Braud was erected at a place called "La Chapelle", near Fréneau, during a procession in June 1915, thus indicating the location of the disappeared church.
This cross is visible from the road leading to the nuclear power plant, on the left, 4 km from the Paillerie roundabout.
