Astonishing discovery of old fort reveals explosive history | What On Earth | Science Channel

First day?

Biggest concrete wall? Guess you have never heard of the vatican.

"This is definitely a fort"
Jesus.

Ancient mud flooded structures jon levy talks about

It looks like it was from canon balls.

it's a silver sluice.

Could be because there was a war there with can and firehmm

Those are direct impacts mr know it all

Looks alot like a place we have in Belgium, Diest to be precice, the city used to have a functional fortress with an entire wall

Not really depending on how long it's been around it could've came from weakness in the concrete when it was being built

Bad data in bad data out. Stop reading the his story books.

He definitely has a firm grasp of the obvious.

Americans used to express "Holy cow"! Why not "Holy pig"! Can anybody explain it to me?

Thats a toilet

I would believe you, but the grass has been cut

Pockmarks?

Definitely a fort ? Hahahaha hahahaha. 🌎✌️🌍

Another wanna be

See when he discovered a waterfall at Niagara

Daaaaaaa !

Climbing grips

No possibility that was an execution site?

What is in the middle? Timeline?

And Is WHERE ?

MAYBE Still a base ....dumb

For execution by firing squad?

Wait so this guy “discovered” a fort that has been known about for ages. Umm… ok. 🙄

It wasn't a fort.... You're just trying to hide the truth about alien explosive diarrhea from us¡! 😮👽💩
😂😂

Oh boy!
This guy is smart. I was thinking it was a 7/11 but a fort makes more sense

Maybe target practice?🤓🤷‍♂️

The Maginot line, fallschirmjaegers eat those forts for breakfast. 😉

😂😂😂 umm I dont need to be a scientist to know it was part of a fort, my God people and companies will do anything for views 😂😂

Cool

No comment, thanks

WWII rediscovered again. Hope younger pepole appreciate it. I feel history will be lost if you in younger generation keep educating

Why is that artillery & not erosion or resulting from a poor mix of the concrete? I've seen potholes in driveways that looks like that from a bad concrete mix. So, why not here?

Fake drama is repulsive

Pretending you didn't know what this place was and then finally stating that it's a fort -- as if you just figured that out -- was a fail.

These shorts like this are so much a waste.

Considering it's under ground it's a bunker not fort

A concrete wall that hasn't been maintained has pieces falling out of it?

aRtIlLeRy ShElLs Are tHe OnLy PoSsIbLe ExPlAnAtIoN!!

Lol. Your professional assessment is that it's a fort. Damn, your good Sherlock.

Han beings in history have created so much diverse inventions. Is there a historical event connected?

DISNEY LAND. YEP
