Ouroux was inhabited very early on by the Celts (Gauls), who are thought to have built the Loutière camp (near the hamlet of Montpensy). During the Gallo-Roman period, the presence of humans is also attested to by the existence of brick wall foundations and pottery. This was also the period of communications with the Roman roads, in particular the road linking Autun to Orléans, which passed through Ouroux. The village thus derives its name from the Horroez period, from Horreum, meaning food and fodder shop. The name also has a Latin origin: 'Oratorium in Morvento' from oratoire (place of worship).
This route takes you to the Chapelle du Banquet and its splendid panorama. This small Romanesque building was built on the initiative of André-Marie Dupin, lord of the Château de Raffigny, located on the hill opposite. Very attached to the Morvan and its opening-up, he was responsible for building many Morvan roads and bridges, as well as the Settons reservoir. He commissioned the Parisian architect Lenormand, who had already designed the churches at Dun les Places and Vandenesse, as well as La Madeleine in Paris. This little chapel, known locally as "Notre Dame du Morvan", was built in 1858 as a tribute to Mr Dupin's late wife.
