Doomsday Castle
Doomsday Castle is a reality [television series] on National [Geographic Channel], that was canceled in 2013, showing the lives of Brenton Bruns and his five children preparing for the end of the world, in a castle he has built near Pickens, [South Carolina]. The show is a spin-off of Doomsday Preppers; Bruns and his castle were originally featured on the season 2 episode "No Such Thing as a Fair Fight".
Bruns says he built a castle to survive an electromagnetic pulse, since a castle can survive without electricity and defend against raiders. It started as a bunker in 1999, and is continuously being added to. Bruns states that his property is covered with booby traps, and his neighbors are "serious preppers with lots of guns".
