The village has a rich historical past. It was the seat of an important villa in the Gallo-Roman period and numerous vestiges are regularly brought to light. Opening up towards the Grosne valley, on the road to Chalon, Sercy and its chateau, which is classified as a historical monument, have long defended the interests of the Abbey of Cluny. Together with the church of Saint-Vincent, this magnificent fortified plain château with its singular architecture sits majestically in the heart of this rural village. This 15th century chateau is notable for its hourd (a wooden gallery built at the top of a rampart for defence purposes), of which there are only a few examples left in France. It belonged to a governess of Charles Le Téméraire. The last Duke of Burgundy spent part of his childhood in this place. Although
it is private property, you only have to park on the small parking lot in front of the pond which separates the castle from the road to admire it at leisure. Not far from there, on the banks of the Grosne, you can see the mill of Sercy which was equipped in 1903 to produce renewable electricity for Saint-Gengoux-le-National.
