We all know from history class, as well as TV shows, movies, and books, that all of America’s gold is kept in a vault at Fort Knox. This bullion bunker in the heart of Kentucky, of all places, is a mysterious, secret, well-guarded place that few people have seen. Fort Knox is, after all, the most secure place in the United States. Aside from the piles of gold bars, what else do we know about this fortress of golden steel? Let’s look at some of the little-known facts about Fort Knox.

Fort Knox is an octogenarian

Fort Knox was constructed in 1937, meaning it is more than 80 years old now. The original construction cost of the gold bullion depository was $560,000, which would be around $10 million in today’s money. It was built with more than 4,200 cubic yards of concrete and 16,000 cubic feet of granite, with 750 tons of reinforced steel and 670 tons of structural steel. Despite its age, the structure is solid and impenetrable. The roof is so strongly built that it is bomb-proof. The main vault door cannot be breached by explosives, blow torches, or drills—it is 21 inches thick and weighs more than 20 tons.
