Sometimes you can't just trust a regular lock to keep your inner sanctum protected. And that's when you need one of these beautiful locks from hundreds of years ago. Back in the Renaissance, people knew how to lock things down in style. Here are the most stunningly ornate antique locks.

Who ye are ye come by stealth
To impare my Master's wealth.

DISCUSSION
I once read that back in the day complex (or numerous) locks weren't so much about the security provided by the locks themselves as they were a statement about how much you cared about the contents, and how bad you'd break their balls if they messed with it. It's kind of like a biker leaving his helmet on his Harley parked on the street: go on, mess with it... I dare you!
