"The Prague astronomical clock, or Prague orloj (Czech: Pražský orloj [praʃskiː orloj]), is a medieval astronomical clock located in Prague, the capital of the Czech Republic. The clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the oldest one still working."

Great shot - and you've captured the detail around the clock exceptionally well too - I've been there, and taken photos, but hadn't noticed the skeleton on the right hand side!
Oh, I'm so excited to see this shot as I used a "Creative Commons Licensed" photo of the same clock when I did some freelance writing for the institution I work for on Time Management for adjuncts! And here it is from you! Lovely.
