Built in 1830, it was equipped with a steam engine at the beginning of the 20th century, then transformed into a flour mill in 1916.
Unable to meet too much demand and being located far from the railway axis, it was abandoned in 1933. It gradually fell into ruin, leaving only a tower covered with ivy and brambles.
It was Gabrielle Mignen, descendant of the former owners, who offered it to the town in 2002 and financially supported its restoration.
Today, even if the wings are missing, the Beaulieu-sous-la-Roche mill has regained its proud appearance and can be visited during exceptional openings to the public, notably during the European Heritage Days. It is also the starting point of the Sentier des Trois Moulins, one of the eleven hiking trails around the town.
