Yesterday's Astronomy Pic of the Day was a panoramic view from the top of Mount Everest.

There's a better, interactive version, here. There's a ton of that kind of stuff at that site that you can find yourself from their home page. I picked out a few when last I linked there four years ago.

There's also a World Wide Panorama site, here, and a collection of panoramas at the Library of Congress here. There's even some interesting stuff at Wikipedia. 1851 San Francisco is neat.

Great stuff.
