A family has made an amazing discovery while digging up their backyard, discovering pieces of history dating back to the 1860s.
Christy Kallemeier-Keene, from New Madrid in the US state of Missouri, posted several photos of the incredible find to Facebook.
"When digging in the yard you find a civil war bunker!" she captioned the images. "You can’t make this stuff up!"
Photos show a square in the ground partially covered by dirt and roots with a timber-lined entrance. Once inside the small space is lined with wooden beams.
Amazed Facebook users commented on the family's find, amazed at its condition.
"That is awesome to say the least!!" one user exclaimed. "Glad it wasn't accidentally destroyed!!
"Who would of thought right in your own backyard," added another. "That's so cool."
Locals amazed by historic find
Ms Kallemeier-Keene later commented on the post saying they had someone from the State Historical Society of Missouri come out and inspect it, but they had to cover it for safety issues.
"We had to cover it back up," she explained. "So a couple of timbers [were taken] for the museum and pictures are all we got."
She later added it was in a "bad spot" in the yard to keep it uncovered.
The civil war lasted for four years from 1861 to 1865 over the status of slavery in the United States, so the bunker was presumably built between those years.
It's unknown if the bunker was used at all, with Ms Kallemeier-Keene saying they took a metal detector down there but didn't find anything.
Last month, a family was surprised to find what appeared to be "death masks" scattered around their property in California.
Death masks were made to capture the subject's facial expression immediately after death.
