In the Middle Ages, the town was called Castrum Berzoriacum. During the Hundred Years' War, it was temporarily caught between the English and French fronts; it was destroyed during the Huguenot Wars. It was also fought over during the Vendée Uprising at the time of the French Revolution.

The church was mentioned as early as 1090, and parts of Notre-Dame date back to the 12th century. The late Gothic, square choir area dates back to the 15th century. At the mid of the 16th century, the 56m-metre-high massive tower was added.
