"Sure, it's a graveyard—but Greyfriars Kirkyard, which has been housing the dead since the late 1500s, is no ordinary cemetery. In fact, it's one of the most popular tourist destinations in Edinburgh. The dog statue outside the gates pays tribute to Bobby, the faithful canine who laid at his owner's grave for 14 years; it's considered good luck to rub his nose. Check out the caged graves (known as mortsafes), made to protect cadavers from being exhumed and sold to Edinburgh Medical College for dissection—a huge problem in Edinburgh during the early 19th-century." - Freya Herring
