Between the two villages, along the stream, there is a typical old mill, which is probably on the same site as that which belonged to the count of Foix and which is already mentioned at the end of the Middle Ages.
In 1838, a criminal case in Orus hit the headlines: Marguerite Dhers, widow, had a romantic relationship with a resident of the village to whom she was not married. She gave birth to a child who died a few moments after birth and bore signs of beatings. Denounced and tried, she was pardoned because the child born prematurely had no chance of surviving. This type of business was not isolated in the XNUMXth century because women who had a child out of wedlock were ostracized from society.
