Restoration of a Lime Kiln and creation of an ecological museum (Prize of the Rhône Alpes region Heritage in 2005)

The Cons-Sainte-Colombe Lime Kiln, stands delicately on the remains of old foundations stones. It consists  of a floor of old timbers and a roof with a special pitch. The mobile shutters look out sparingly onto the dominating heights of the Bauges’. It is as if the Lime Kiln of Cons-Sainte-Colombe had always been there.

Inside, a balustrade echoes the shape of the brickwork used in the combustion chamber. A floor entirely made of glass offer a clear view of the last remnants of the previous batch. On the roof, right at the top of each chimney, circular glazed openings clearly reveal the natural progress of the fumes and flue gases.

The presence of waste from the fiery processes, especially from the inner spaces, evokes a clear image of the industrial past.

A small and sparkling light evokes the glowing red light of combustions.




The Cons-Sainte-Colombe Commune is located on the plain which connects Annecy to Ugine. François Chatillon and the local Archeologist urged protection of the old Kiln to which the Commune responded in a positive way by launching the project. It was conceived in 2005 by Architect François Chatillon, who decided to protect the Lime Kiln, situated at the entrance to the village, on the mountain side. Then, he planned to establish a small local office for educational purposes, to inform the public of the industrial past of the locality, which disappeared in Cons at the end of the 19th century.


The historical and heritage interest, plus the exceptional quality of the site itself, convinced the Commune and its General Council to finance the whole conservation project. The lack of iconographic and descriptive documents providing the accurate informations about how the Lime Kiln used to work inthe 19th century had a consequence on the conservation project. It was decided to retain the entire operating parts without modification. The evocation of the inner workings is revealed by a contemporary design.
