A grandfather has uncovered a 17ft deep well under his living room floor.
Colin Steer believes the find may date back to medieval times, which could make it 500 years old.
The 70-year-old has spent the last decade digging out the well after he found it while redecorating the living room of his home in Plymouth, Devon.
He noticed a dip in the floor while carrying out DIY, which led him to uncover the well.
While digging it out, Steer found what he thinks is the leather casing of a sword, which he believes could date the structure to the 1500s.
"Around 10 years ago we were doing some decorating and I was replacing floor joists when I noticed the floor dipped near the bay window in our front room,” he said.
"I immediately thought someone must have buried someone under there or that we had a sinkhole.
"Since that moment, I decided I was going to dig it out and see what I would find.
"The hole is currently 17ft deep and there is about another four or five-foot that I want to dig out when I eventually get round to it.”
Steer said there is about 4ft of water at the bottom of the well, making future digging a muddy process.
"I don't think my wife, Vanessa, would be too keen if I got that all over our front room,’ he said.
"Although she does find the whole thing very interesting too."
He said he would eventually like to extend the walls of the well into the living room and turn it into a coffee table.
"I think it would be a great feature for our front room,” he said.
Steer has found a coin from 1725 in the well while excavating, and believes the depth of the structure means it could have been used for feeding animals or up to three families.
The hole in the couple’s living room is covered by a sheet of Perspex and a trapdoor.
Their grandchildren love to look through to enjoy the unique feature, Steer said.
"It is a good thing to show off to people as it is not something that you see everyday,” he said.
"I have actually even tried some of the water that is at the bottom of the well. It was really clear and tasted fine to me.
"I am going to get it tested for bacteria and if everything came back good then I could even bottle it up and sell it."
