Documentation of marbles, granites and more used in American buildings and monuments
Natural stones used in American buildings and monuments are documented in a recently launched database by the US-National Park Service. In December 2015 it contained more than 130 sorts from the US and a few from the United Kingdom. The website named the „National Building Stone Database“ gives the location of the quarry and its status (active or not), the names of the producers, a description of the stone and much more.
The National Park Service writes on its webpage: „The database is a work in progress. We’re continually working to expand our catalog of stones and improve the functionality of the web site.“
