Guessed by Robin King this is indeed the Liberty Bell in Philadelphia. I wanted to do a mystery image game with it before I uploaded other photos from my most recent US trip.
Security is high as anything if you go and look at the bell, so if you are shopping in Philly, go to the bell first. Luckily I had a receipt for my goods so the woman at the desk did not have to unwrap every single item in my bags :-P
Philadelphia, PA, USA. 20th March 2013.

As is, straight from camera.
