ABSTRACT
ABSTRACT: Restoration of historical buildings often takes place without knowledge exchange between architects and geologists. Architectonic heritage should be preserved under the same regime within which it was originally conceived, using the same natural stone for its construction, which most of the times consisted on local material sourced from nearby quarries. However, the non existence of documentation of historical quarries or a precise description of the natural stones used in many historical buildings often leads to the inappropriate action, both detrimental to the building itself and the cultural heritage of a region. National and international networks should join efforts to cover the lack of information.
