The incredible 1900-year-old discovery comes after workers at the North Brian Water Company replaced a power grid on the West Road side near Newcastle, England.

Among the regular works, a team from the Water Company unearthed a section of the famous Hadrian Wall, three meters below ground level, east of the Two Ball Lawn Roundabout.

The newly discovered part of the wall is believed to have been one of the earliest stages of the landmark, as the later stages used very small stones.

At the time of the invention, Northbrian Water was part of a 5 5 million plan to improve the quality of tap water for half a million consumers on TimeSide.

Graeme Ridley, Northumbrian Water Project Manager, said: “We are pleased to be able to make this brilliant discovery and to work closely with archaeological services to ensure that it is properly preserved.

“We have completed the work in this area and are doing this important work with the aim of protecting our water supply in the future and ensuring that our customers have access to the best and highest quality tap water.”

Philip Hunter of Archaeological Research Services Ltd said: “Although Hadrian’s Wall Route is well documented in this part of the city, it is always exciting to find the remains of the wall.

“This is especially true in this case where we think we have found a part of the initial phase of the wall, and it is always a pleasure to work with Northbrian waters, which take the preservation of archaeological remains very seriously.

Northumbrian Water said the water pipe could be angled to leave a plug around the excavated rock.
