Chillon is an ideal example of a conservation and restoration building site. Since 1892 work has been overseen by a Technical Commission of architects, historians and heritage specialists.
Work on the buildings can be of very different nature and importance, from minor repairs to major restoration projects.
All work is carried out respecting the current ethical standards for heritage buildings. All additions are designed with a modern style, while conservation and restoration work are integrated discreetly into the fabric of the buildings.
A particular aspect of this work in the case of Chillon is that the castle stays open all year round. Therefore the needs of the construction projects have to be fulfilled while ensuring that the public enjoys visiting the castle as much as they have the right to expect.
