The imposing castle "Château de Fléchères" is now open to the public and can be visited. But that wasn't always the case - the property can look back on a very checkered history. The castle itself dates back to the 17th century, but was built on the walls of an old 12th-century fortified building. First owned by various noble families, it passed into the hands of a gang of Mafiosi from Lyon in the 1970s. Later in the 1980s the castle was almost deserted and partly looted before being listed as a historical monument in 1985.
