Trinity Mystery Spot

I decided to take a picture of this particular elevator because it is a place that I visit everyday. It is a significant location on campus. I'd say that a large portion of the sophomore class visits this location on a daily basis. I edited this photo because I thought it would make the picture more interesting. I changed the colors because I found the colors in the original dull. However, in my edited version,the contrast in colors make the image more captivating. I think it has a mysterious look to it, especially with the word "danger" in the bottom. Can you guess where on campus this photo was taken?
