Centuries ago, our ancestors discovered how to harness the power of the elements – which, while helpful and useful, could also be a threat as untamed natural forces – for various purposes, thus eliminating the need for human or animal muscle power. A good example of the engineering skills of earlier generations are mills like these: the heavy millstones, used for grinding grain or pressing oil, could be powered by wind or – as in this case – water.

Astonishment! This is the feeling that dominates when discovering GALLERIA CONTINUA / Les Moulins, near Boissy-le-Châtel. A contemporary art gallery that follows in the footsteps of its renowned Italian, Chinese and Cuban sites... GALLERIA CONTINUA / Les Moulins has two sites, which are located in former paper mills. Located in Boissy-le-Châtel, in the Grand Morin valley near Coulommiers, the Moulin de Boissy, at 46 rue de la Ferté Gaucher, and the Moulin de Sainte-Marie, at 48 rue des Papeteries, have a rich history whose first written traces date back to the 14th century. Guided by the rhythm of the seasons, GALLERIA CONTINUA / Les Moulins hosts several times a year projects and exhibitions of monumental works by artists from five continents. Since 2007, the Moulin de Boissy site, a renovated former factory of 10,000 m2, has embraced its new artistic life with, for its first three years of activity, 30,000 visitors from all over the world. In 2010, Galleria Continua took on a new challenge by acquiring the former Sainte-Marie paper mill, one kilometer from the Moulin de Boissy. The Moulin de Sainte-Marie extends over 15 hectares with 30,000 m2 of built surface area. Each space has its own function and therefore benefits from architectural and spatial individuality and hosts in situ projects by international artists such as Etel Adnan, Kader Attia, Daniel Buren, Subodh Gupta, Anish Kapoor, Kiki Smith, and many others. Every Wednesday, Thursday, Friday, Saturday and Sunday from 12 p.m. to 6 p.m. Exceptionally closed on January 1st, May 1st, July 14th and December 25th. Doorbell on the building at the entrance.
