360 Cities is back with another record, this time for the World’s Largest indoor photo: An impressive 40 gigapixel image of the Strahov Library.

This image was created from 3,000 individual photos stitched together into a single image that is 280,000 x 140,000 pixels. That’s around 40 gigapixels, or 4000 megapixels. If you printed this photo it would be 23 meters (or 78 feet) long!

It really is beautiful, although I wish a book had been left open in the room so that you could read it at full-zoom.
