A charming town in Franche-Comté, part of the Holy Roman Empire until the Treaty of 1678. Very prosperous in the Middle Ages, thanks to its trade and artisans. A cloth market was established there as early as the 14th century, after Joan of Burgundy, Countess of Franche-Comté and Queen of King Philip V the Long of France, brought weavers from Paris. From June 14, 1354, until the Revolution, the bourgeoisie of Marnay had a charter of emancipation that guaranteed them security and prosperity: "Whoever has a house and keeps a fire in the town will be a bourgeois." This charter allowed the inhabitants to administer the town themselves and thus build ramparts and create the individual gardens that can still be seen today.

Characterful Comtoise town which was part of the Holy Roman Empire until the treaty of 1678. Very prosperous in the Middle Ages, due to its trade and its artisans. There has been a cloth hall there since the 14th century, after Jeanne de Bourgogne, countess of Franche-Comté and queen of King Philippe V the Long of France, brought weavers from Paris there. From June 14, 1354 and until the Revolution, the bourgeoisie of Marnay had a charter of emancipation which ensured them security and abundance - "anyone who has a house and keeps fire in the village will be bourgeois". This charter allowed residents to administer the city themselves and thus build ramparts and set up the individual gardens that can still be found there today.
