Once a Dominican Monastery with school, dating back to the 17th century, these buildings later became army barracks during the French Revolution. Later on, the buildings served even more different purposes, from a cotton factory to a brewery, storage building for the National Railways and a basket weaving company. In its final years, before it became abandoned, the building was once again a school, this time a technical college. Nowadays the buildings are protected and are being renovated.
