There's a huge amount of subterranean space that we're not aware of around us all the time. For those of us who live in suburban and rural areas, it's not unlikely that one of your neighbors has a bunker underneath their house that you don't know about.

But in modern history, we've really outdone ourselves. Garrett will be our guide to the fascinating world of architecture for the end times. And we're going to find out why today we're going through a true bunker renaissance.
