A ROMAN mosaic has been discovered underneath land being developed for an Aldi supermarket.

Oxford Archaeology, who carried out the work for developer Angle Property, deemed the mosaic a "pretty exciting find".

The discovery was made in Warrington Road in Olney, Buckinghamshire.

Archaeologists believe the mosaic belongs to the Durobrivan group from the East Midlands.

They wrote on social media: "We can now share a pretty exciting find. A Roman mosaic, probably belonging to the Durobrivan group from the East Midlands, that we uncovered during excavations at Olney, Buckinghamshire on behalf of Angle Property.

"There is a previously known Roman settlement at Olney, so when work started, we knew there was the possibility to find some pretty cool structures and finds but...a mosaic! Wow!"

Project Manager John Boothroyd said: "This fantastic mosaic far exceeded the expectations".

He said to the BBC: "Due to the site location we anticipated some notable Roman remains, but the discovery of this fantastic mosaic far exceeded those expectations.

"To be able to preserve remains of this quality and importance is a brilliant outcome, and one that could only have been achieved with the support of Angle Property."

The site, where the mosaic was found, is being prepared for the construction of a new Aldi supermarket in Milton Keynes.
