Himeji Castle in Japan at sunset. It's one of only 12 surviving original castles in Japan and is a world wonder in my opinion. If you are in Japan DO NOT miss seeing this castle.
Saw this staircase online, found a contact name, was allowed to photograph for 10 minutes, so I had to work fast! Turned out I had about 45 minutes as the contact person didn't kick me out. I didn't notice or think about moving the black mat at the bottom, but I probably shouldn't have started messing around with things when they were nice enough to let me in to shoot.
This is one of the buildings on the campus of Cornell University in Ithaca, New York State. I was exploring the campus and knew that I should come back here after sunset when the lights would be lit up.
