abstract_textpAlpedrete granite is a monzogranite quarried in the Sierra de Guadarrana (Spanish Central System) foothills in and around Alpedrete, in the province of Madrid, Spain. Used as a building material since the Neolithic, it is one of the most representative of heritage granites of Madrid./ppAlpedrete and the surrounding region are characterised by a quarrying culture that has been maintained for centuries. The area is strewn with historic quarries, along with the one presently in operation. Traditional stone cutters who produce hand-finished granite ashlars are still to be found, while others use more modern techniques to achieve new types of products./ppRepresentative monuments including Royal Palace of Marid, Alcala Gate and the National Library owe their good conservation state largely to the petrophysical properties and durability of Alpedrete granite. In addition to its use in a substantial number of heritage buildings in Madrid, this stone is also found in most of the city's housing, urban furniture and cobble-stoned streets and nearly all the rural architecture in the Alpedrete area./ppThis paper discusses the petrological and petrophysical properties of Alpedrete granite, as well as its durability, historic use and quarries, in support of its nomination for the "Global Heritage Stone Resource" designation./p/abstract_text
