One of the largest indoor photos ever posted online comes in at over 40 gigapixels and is a fly-around-the-room tour of a library! How awesome is this place?

This single image is made up of more than 3,000 images stitched together. If they were printed out the site claims the photo would be 78 feet long!

This gargantuan gigapixel image has been online since 2011, showing the world the largest and smallest details of the Strahov Library. The Strahov Llibrary is in Prague inside the Strahov Monastery.

I could just watch this image all day checking out all of the spines in such detail. What an amazing library. This 40 gigapixel image is very cool, but I bet this place is something else when seen in person.
