Archaeologists uncover ancient ring ditch
Archaeologists from Pre-Construct Archaeology have uncovered an ancient ring ditch during development works of the Dove Valley Park in Derbyshire, England.
Evidence of archaeological features were first identified from cropmarks and aerial photographs, suggesting the presence of several ring ditches and linear ditches.
Excavations have confirmed the existence of the features through a process of trial trenches, where archaeologists conducted a strip, map and sample excavation to fully reveal and investigate the remains.
Ring ditches are typically a trench of circular or penannular plan cut into bedrock. The term is most often used as a generic description in cases where there is no clear evidence for the function of the site: for instance where it has been ploughed flat and is known only as a cropmark or a geophysical anomaly.

Excavations suggest that the ring ditch is prehistoric in origin, with a similar feature excavated in the vicinity during the 1990’s dating from the Bronze Age.
Archaeologists have interpreted the site as a stock enclosure, an ancient pound for the accommodation of livestock. The study has revealed a possible entrance to the enclosure, with evidence of re-cutting of the ring ditch that suggests maintenance of the site and possible longevity of use.
The long linear ditch is believed to be a post-medieval boundary for the demarcation of land, running west–east to the north of the ring ditch.
PCA archaeologists said: “These discoveries add to our understanding of the area’s rich history and provides fascinating insights into the way our ancestors lived and worked.”

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
