The Hall of Registry is one of the oldest and most treasured places in the North Pole.  This is the special library where information about Christmas and elves from around the world is stored. When you visit the Hall of Registry, you can test yourself on your Christmas knowledge, check out some of Santa’s Top Ten lists, upload your own elf photos, and even send a message to Santa Claus. Just remember: elf librarians are working, so keep your voice very quiet!
