High Security

By Karin Dovring and Folke Dovring

How do we protect the most valuable, the most important, and the most dangerous things on Earth? The answers might be surprising Sometimes guards stand watch 24 hours a day. Other times thick concrete vault walls help keep priceless items safe. From storage caves deep underground to high in the sky aboard the U.S. president's plane, give readers a glimpse inside some of the world's most secure places.
