Looking at the staggering size of the U-505 submarine resting inside its subterranean concrete bunker, the most obvious question is also the most baffling:
How on earth did a 700-ton N**i war machine end up buried under a lawn in the middle of the American Midwest?
The story of its capture in the Atlantic during World War II is legendary, but the sheer logistical nightmare of physically bringing it to Chicago is one of the most unbelievable engineering feats in the city's history.
In 1954, Chicago native and U.S. Navy Captain Daniel Gallery fought to bring the captured U-boat to the Museum of Science and Industry.
Towing it 3,000 miles down the St. Lawrence River and through the Great Lakes was incredibly dangerous, but that was actually the easy part.
Once the massive steel leviathan arrived in Lake Michigan, engineers had to figure out how to get a 700-ton warship out of the water and across dry land.
They engineered a massive floating dry dock, slowly beached the submarine, and then completely shut down Lake Shore Drive.
Using a complex system of heavy steel rollers, winches, and massive tractors, it took crews several painstaking weeks just to inch the submarine 800 feet across the highway and onto the museum’s lawn.
For nearly fifty years, the submarine proudly sat outside in the open air.
But by the late 1990s, the brutal, freezing Chicago winters and relentless snow were causing severe structural damage.
The weather was slowly destroying what Allied depth charges couldn't.
To save it, Chicago had to pull off a second engineering miracle.
In 2004, the museum launched a massive $35 million project to bury the U-boat.
Crews dug a massive, four-story trench right in the museum's front yard.
They placed the submarine on massive teflon pads, slowly slid it into the crater, and then built the massive, bomb-proof concrete ceiling right over the top of it.
Today, when you stand in that underground bunker, you aren't just looking at a war relic; you are looking at a 700-ton puzzle that Chicago absolutely refused to lose.
