Résumé en anglais
Herb Stovel in "Conservation Techniques: Buildings" begins by stating that no technical conservation decision exists outside a philosophical context. Conservation is more an art than a science, technical measures being the means of prolonging the life of a site with important "messages" reflecting its values. The degree to which conservation action enhances these values is the real measure of success and not the ingenuity of the technical solutions. The author looks at ICOMOS as the custodian of conservation on doctrine, accepting criticism of the Venice Charter and encouraging the establishment of other charters like the Burra Charter of Australia or, more recently, the New Zealand Charter; which adapt the principles of the Venice Charter to local conditions. The New Zealand Charter, which is included immediately following this paper; advances conservation thinking by accepting the inevitability of decay in dealing with the heritage of indigenous peoples. Like John Warren, the author pleads, in matters of conservation, for modesty and minimum intervention, the key concept being caution.
