The Conservation Programme of the Côa Valley Archaeological Park: Philosophy, Objectives and Action

Abstract This paper outlines the methodology for the conservation of Côa Valley rock art, as carried out by the Côa Valley Archaeological Park Conservation Programme. It examines the overall conservation environment that has determined this approach, which aims at an understanding of all the factors affecting the survival of the Côa Valley heritage. We stress that although the Programme sets precise guidelines for the examination and testing of conservation work to mitigate the effects of complex weathering dynamics in action, there are no miraculous solutions to ensure the complete longterm in situ preservation of this World Heritage Site. Despite this geological impossibility, we also emphasize that in a human time scale it makes sense to try to conserve significant heritage (such as the Côa Valley rock art) that expounds and explains our history and ourselves.
