Britain's lost Atlantis is thought to have finally been found after falling into the sea 650 years ago.
Scientists have spent decades looking for Ravenser Odd after it was swallowed up by the North Sea in 1362.
The sunken town, dubbed Yorkshire's Atlantis, was once a major stopping place for fishing boats and cargo ship sat the mouth of the Humber Estuary.
Historians and scientists believed it lay at the bottom of the sea around a mile off the Yorkshire coast.
But a new search closer to the shore recently uncovered rocks and stonework just a few metres beneath the water's surface.
Sonar equipment has now been deployed in the hope of finding the harbour walls of the lost town.
Experts say the find would be as legendary as the discovery of Pompeii, after it was buried under volcanic debris, or like uncovering Atlantis itself.
Professor Dan Parsons, a geoscientist at the University of Hull, is now leading a search.
"It’s fascinating, exciting, exhilarating. The exact location of this medieval town hasn’t ever been pinpointed," he told The Sun.
"We now have the tools and the technology to go out there and locate it once and for all."
The team hope to find the footprint of the town including its foundations, harbour and sea wall.
Then they will be able to map it out and create a 3D map, which could then be used to send divers down to the site.
Experts say they now have all the data needed and will be analysing the area under the sea in the coming weeks.
They should be able to confirm whether it is indeed Yorkshire's Atlantis by the end of June.
Phil Mathison, who has devoted 25 years of his life to looking for the town, is equally excited.
He said: "To actually find it, after such a long time, will be the completion of a life’s work. I’m blown away by it all."
The historian explained why the find will be such "an extraordinary discovery."
He told how Ravenser Odd returned two MPs to Parliament and consisted of two chapels, two weekly markets, a court, a jail and an annual fair.
Its ships were a prominent feature in conflicts with Scotland in the early 1300s but 50 years later, the town had vanished.
Ravenser Odd was founded in 1235 and earned a great reputation which saw it mentioned by William Shakespeare in Richard II and Henry VI.
But by 1346, much of the town had been lost to erosion.
It was finally lost in January 1362, when much of the east coast was devastated by a large flood.
Prof Parsons added: "Strategically, it was a perfect place for a port.
"Unfortunately, it’s also located in an area of significant coastal change."
