In October 2025, Archaeological Research Services Ltd commenced work for our client Galliford Try on excavations near Cheltenham, Gloucestershire for Gloucestershire County Council’s M5 Junction 10 Improvements Scheme. This project covers a site of around 30ha and includes comprehensive archaeological works to excavate remains that will be impacted upon, to record them for posterity and to make the information publicly available.

Now halfway through 2026, we’re delighted to bring you some updates of the work that’s been going on and reveal some of what we’ve been finding at this fascinating site. There will be further updates in coming weeks.

The work commenced with metal detecting and we recovered a range of finds that included Roman coins and a small brooch of a type known as a ‘trumpet brooch’, which likely dates to the mid 1st – early 2nd century AD.

Following the metal detecting, stripping of the top soil then began and we were excited to see archaeological features already coming up.

Progress continued to go well late into the year, despite some wet conditions. One of our favourite finds was a well-preserved copper alloy penannular brooch, recovered from a ditch fill. This type of brooch was very common in the Roman period (although actually appeared in Britain prior to the arrival of the Romans) and we think this one may be 4th century AD in date. Very similar examples have appeared at Roman military sites, including along Hadrian’s Wall.

Meanwhile, there was another exciting early discovery, where a stone wall was starting to be revealed that turned out to be part of a corn dryer. This is a feature that was traditionally used for drying grains of barley ready to make beer—where the barley was placed on wooden floorboards overlying a stone ‘oven’, within which a fire was lit in a stokehole that warmed the air. A little like an underfloor heating system!

Elsewhere on the site a human burial came to light where the skull had been removed and placed between the knees of the individual. This is a practice we have come across at several sites before, such as at Black Cat Quarry, and is occasionally known across much of eastern England and the Midlands in the later Roman period and during the transition to Christianity.

That’s it for now. We’ll be bringing you more discoveries from this site soon, so make sure you don’t miss an update by following us on FacebookLinkedInInstagram and Bluesky!
