Google and Art Museums all over the world have worked together to create on-line galleries showcasing over 30,000 pieces of art. Much like Google Maps, Google Art Project allows the user to take virtual tours of galleries, create on-line collections of their own and zoom in to view individual art pieces. Search by collection, artist or artwork. Be aware that not all museums are complete in their tour or the artwork shown. Each individual museum was able to determine what areas of the museum and which artwork was included.
