The castle was built towards the end of the 11th century by Narduin d'Estrabonne. It has undergone numerous modifications over the centuries. It was its transformation into a farm that would have saved it from ending up in ruins at the time of the Revolution. The castle today retains a beautiful appearance, notably with a keep still worthy of the most beautiful castles.

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.

Royal House 15th - 16th century Monument The initial function of this building remains obscure. The Royal House was probably integrated into the city's fortifications, constituting a real barrier between the border district and the town. This defensive role is suggested by the presence, on the southeast facade (river side), of loopholes and firing points. The large interior volume also suggests that the building was used as a warehouse.
