In 1952, Mike's grandfather Jim was approached by the British government. They wanted to buy a 25-acre field at the center of his 2,000-acre farm just outside this small, sleepy village of Kelvedon Hatch. Jim was threatened with a compulsory purchase order if he didn't agree to sell the field, but luckily he was happy to.

"My grandfather said he had fought two World Wars and wasn’t inclined to fight another," Mike says. Despite negotiating a price for the land, Jim wasn't able to wangle a spot in the bunker for his family should the worse happen.

Today, the Parrish family owns the land once again and Mike runs tours of the secret nuclear bunker.
