YouTuber Mr Beast spent 24-hours inside a huge Doomsday bunker with its own pool, library and gym.

The 14-level luxury unit is a far cry from what of us would think of when we hear the word ‘bunker’ and basically looks like a fairly decent hotel inside.

Exploring the bunker, a shocked Mr Beast said: “To be honest, I completely forgot I was 11 stories deep underground. This feels like a normal house.”

And a very fancy house at that, because as well as its own pool area and gym it has a cinema, sauna, games room and even a rock-climbing wall.

It also boasts its own self-sustaining food supply of fresh vegetables and a fish tank, with the waste from the fish fertilising the plants – clever, eh? And that’s alongside an impressive pantry that is really more like a supermarket.

The giant silo was built back in the 1950s and was built to withstand a nuclear strike, most of them were then left abandoned, but this one was taken over and transformed into the rather marvellous looking building you can see in the video.

Mr Beast and his pals spent a full day in the bunker, taking advantage of the whopping pool, took in a movie at the full-size cinema and had a go of the climbing wall, before all enjoying a good night’s sleep.

In fact, the trio liked it so much they didn’t want to leave, which is fair enough, because it looks bloody amazing.

If watching the clip has got you keen to follow in Mr Beasts footsteps, the silo offers ‘survival condos’. But if you fancy getting one, you’ll need deep pockets as a full-floor condo suite will set you back an eye-watering $3,000,000 (£2,396,790).

However, you get much more than just the unit, because the package also boasts ‘mandatory training, a three-year per person food supply, fully furnished and custom designed interior, special equipment for registered members’.

The full-floor units accommodate six to 10 people, so you can split that three-million-dollar fee ten-ways.
