One of the amazing memories of my trip to Europe was visiting the Vatican and developing a kink in my neck from marveling at the ceiling in the Sistine Chapel. No photography is allowed to preserve reverence in what many consider not only a cultural heritage site, but a holy site. This link is the next best thing to being in the Vatican staring at the Sistine Chapel. We might not be able to travel the world with our students, but this can help us bring the world to our classroom.
