Nice.
Using Google Maps and the magic of Street View mode, anyone could take a virtual through the entire Palace of Versailles in France. All in stunning detail, 360 degree spinning in any direction, with easy point and click exploration mobility. See below..
This is very cool for the Google and Versailles officials working together to make this happen. Of course, this could never come close to personally being there. However, there are many in this world who will may never have the chance, money, time to ever witness this marvel in person. At least with this, one could appreciate the beauty of the total sum of its architecture, art, history from any computer.
There are probably others. I will have to look into this another time, to explore and discover. If anyone knows or could find a list (not finding much on this at the moment), please comment below.
