TOP 15 LARGEST UNDERGROUND Structures 

great video, some time ago I created a video that talked about how to survive in a bunker, I liked this ranking! 💛

I've been in Subtropolis

There are 30,000 particle colliders on earth? Is there some home version available I don't know about?

💪🏻🤘🏻💪🏻🤘🏻

Here before the 1minute mark!😮

In Europe they told us Raven Rock might be the biggest of its Kind . I was in Co Colorado Springs at Cheyenne Mountain before 09/11 and then i got told that would be the place to be for the last President in Office before bottlecaps will be the way to FLEX infront of your crush😂

As usual, he who has the most money gets to live. What a great system to decide such things...

First can you say hi

15:58 my wall is 10x thinner than this door !!! 🤣🤣

I’ve been subscribed and keep the bell on

That vault is not sterile! The off-gassing from all that glue and cardboard taints the seeds. Even below freezing stuff off-gasses, called sublimation.

Unfortunately Oppidium is still only plan. Located near Cesky Brod in Czech Republic.

"The 7000 square foot facility" - This sounds wrong. The area of an ice hockey rink is 17,000 square feet. Did you mean "7000 square meters" (75347 square feet) ?

The largest cavern hall for public use is Homestrand Station. Gjøvik Olympic hall is wider, but Homestrand station is longer and taller.

One thing you forgot to mention Churchill's bunker had no 🚽 shitter! It had everything but that 😂

I live in Northen Europe's Scandinavian Finland and I've visited in Norway on july, it's really beautiful country with arctic sea and HUGE amazing mountains, in Norway you really feel to be small. Norway's seed vault is really interesting place where is every plants seeds of the world and that underground icehockey place looks interesting too and I've heared there is underwater tunnels in Norway too and here in Finland we have underground metrostation and icehocky area but only in Helsinki. I really like live and being Northen European people. 🌍⛰️🏞🌊❄️🚇🚝🇫🇮❤🇧🇻

While people go hungry. No man among you should go hungry. Put yourself in their shoes. Take this down. I don’t care.

Yeah but what about the bigger underground structures we aren't allowed to know about

I remember when this will was a conspiracy

Biden's from Delaware not Pennsylvania

That bunker is for the public,because nobody knows where the president go be,this a secret security. 16:13
