Considering how long this planet has been in existence, it's safe to say that every single home in this world has something of historical significance hiding underneath it.
However, that doesn't make it any less special when somebody finds something important underneath the soil in their backyard.
On the subject of underground discoveries, take a look inside this nuclear bunker made out of old school buses. This is something you really need to see...
For example, earlier this month, a very extraordinary discovery was made in the very ordinary backyard of an unassuming man from Middlesborough, England.
Chris Scott had been planning a big renovation project in his garden for years, so when he commenced with the work he thought he knew exactly what he wanted his lawn to look like.
However, all of Chris' plans were thrown out when a builder, who was helping him bring his garden to life, encouraged the homeowner to open up a hatch which was partially submerged under grass.
Chris was initially skeptical of this plan, for he'd always assumed the hatch was nothing more than a drain cover.
"It just looked like a drain cover. The neighbors had mentioned a bunker but I hadn't thought any more about it," Chris told The Daily Mail. "I was talking to the builder about it while we were having a cup of tea in the garden and he said, 'Come on let's have a look!'."
And that's just what they did!
Check out the moment Chris ventured into the bunker, where he found something that transported him back in time...
