"Not everyone is fortunate enough to be able to travel to the Loire Valley to see these wonders with their own eyes," the Internet giant's Paris-based cultural institute said in a statement on Tuesday.
Virtual tours and 3D
Thanks to Street View image capture technology, people can take virtual tours of Chenonceau, Chambord, Azay-le-Rideau and 15 other of the national treasures strung along the Loire in central France, including spaces that are normally off-limits to the public
Seven of the sites can be overflown in three dimensions.
Another technology, Art Camera, homes in on details of an artwork that are invisible to the naked eye, such as the Oriental ceiling of the Villandry chateau, the Apocalypse Tapestry of Angers and the frescoes of Fontevraud Abbey.
