The Château de Saint Brisson sur Loire was a massive and exceptional fortress with ramparts 20 metres high and 4.5 metres thick.
Strategically located, it overlooked the Loire at the end of the province of Berry, not far from Orléans and Burgundy. This branch of the Loire has since been drained to make way for the Canal
Latéral de la Loire (see the illustration below, dating from 1600, showing the Loire in front of the castle).
The history of the castle dates back to 1061, when we find traces of its existence in the texts of its lord, Robert de Saint Brisson. In 1135, Louis VI, known as Louis le Gros, King
of France, besieged the castle and destroyed it. In fact, its owner at the time took advantage of the location of his fortress to plunder merchants and travellers passing through.
The castle was then owned by the Counts of Sancerre until 1290, when it was rebuilt. It then passed into the hands of the de Nevers family and, in 1567, to the Seguier family. The Seguiers
decided to turn it into a residence rather than a fortress. To this end, the building underwent many transformations.
During the Revolution of 1793, almost half of the castle was demolished.
In the 19th century, the castle was renovated and modernised.
The last descendant of the Saint-Brisson family donated the castle, which was in a poor state of repair, to the Town Hall of Saint-Brisson in 1987. The outbuildings were then sold and the château
returned to private ownership in 2015 when it was sold to the "Tous au Château" company, which undertook to keep it open to the public.
