HS2 dig unearths Roman market town in Northamptonshire: Ancient artefacts reveal how 30 Iron Age roundhouses were 'Romanised' into a wealthy trading settlement almost 2,000 years ago

  • Archaeologists uncover numerous Roman ancient artefacts on a route of the HS2 high-speed railway project
  • Findings include cremation urns, gaming pieces, shackles, a snake-head brooch and over 300 Roman coins
  • Experts say there was originally an Iron Age settlement at the site which vastly expanded in the Roman period

Archaeologists working on HS2 have shed light on how an Iron Age village in Northamptonshire was transformed into a wealthy Roman trading town bustling with traffic almost 2,000 years ago. 

Stunning discoveries made during a dig of the site near the village of Chipping Warden – known as Blackgrounds after the black soil found there – include cremation urns, gaming pieces, shackles, a snake-head brooch and more than 300 Roman coins. 

Evidence suggests the settlement was established in about 400 BC when it was made up of more than 30 roundhouses, but that it greatly expanded during the Roman era around 300-400 AD, with new stone buildings and roads. 

A team of around 80 archaeologists working on the HS2 high-speed rail project have spent 12 months excavating Blackgrounds, which is one of more than 100 sites to have been examined between London and Birmingham since 2018.

Experts say the remains of the Roman trading town mark 'one of the most significant archaeological sites' uncovered during the controversial £100 billion train line project. 

Before HS2 workers build bridges, tunnels, tracks and stations, an 'unprecedented' amount of archaeological work is taking place along the line of route, to ensure concrete isn't dumped over the secrets of Britain's past. 

This excavation work offers a 'unique opportunity' to tell the story of Britain, according to HS2 Ltd, the state-funded body responsible for delivering the line, although so far its construction been hugely controversial for its destruction of historic buildings and nature spots.

The presence of such a significant archaeological site in the area has been known since the 18th century, but recent geophysical surveys have revealed the original Iron Age part of the site and the artefacts from the Roman settlement. 

Site manager James West, from the Museum of London Archaeology Headland Infrastructure, which has been excavating the site, said the dig had 'surpassed all expectations'. 

'This is certainly one of the most impressive sites MOLA Headland Infrastructure has discovered whilst working on the HS2 scheme,' West said. 

'A particular highlight for me has been understanding the emerging story of Blackgrounds, which we now know spans multiple time periods.

'Uncovering such a well-preserved and large Roman road, as well as so many high quality finds, has been extraordinary and tells us so much about the people who lived here.

'The site really does have the potential to transform our understanding of the Roman landscape in the region and beyond.' 

Running through the site is a Roman road measuring 32 feet or 10 metres wide, which is huge by typical Roman standards – most Roman roads were around 13 feet (4 metres).

WHY IS HS2 CONTROVERSIAL? 

HS2, which is estimated to cost more than £100 billion , aims to provide a high-speed rail service linking London and northern England. 

But according to Wildlife Trusts, construction of HS2 is resulting in the loss of ancient woodlands, nature reserves, wildlife refuges and more. The charity calls HS2 'a grave threat to the UK's ancient woods, with 108 at risk of loss or damage'. 

Critics question whether HS2 is worth its ballooning price tag especially after a pandemic that might permanently change people's travel habits.

The first phase linking London and Birmingham is due to open between 2029 and 2033, according to HS2 Ltd.

The width indicates that the settlement would have been very busy with carts simultaneously coming and going to load and unload goods – a 'very active area'. 

The wealth of the settlement is likely to have been based on trade, both from the nearby River Cherwell and via the Roman road. 

The discovery of over 300 Roman coins is an indication that a significant volume of commerce was passing through this area as the village developed into a wealthy town.  

The archaeologists also found the settlement divided into domestic and industrial areas, with evidence of workshops, kilns and well-preserved wells.

In one part of the site, the earth is bright red, suggesting the area would have been used for activities involving burning, such as bread-making, foundries for metal work or a kiln.

Other artefacts found during the dig highlighted the wealth of the inhabitants, such as glass vessels, highly decorative pottery, jewellery and even traces of the mineral galena – a substance that was crushed and mixed with oil to be used as make-up.

A particularly interesting discovery in the dig has been half a set of shackles, similar to those recently found at an excavation in Rutland

Unlike those uncovered in Rutland, the shackles found at Blackgrounds are not associated with a burial but may suggest the presence of either criminal activity or slave labour. 

Roman shackles (pictured) were also discovered, suggesting that criminal activity or slave labour were part of the settlement

Blackgrounds consists of the Iron Age settlement, which was unknown until experts conducted geophysical surveys, and the Roman settlement. 

Researchers had wanted to establish whether the Iron Age site and Roman site existed independently of each other, or if the Iron Age settlement continued to exist into the Roman period.

Evidence suggests the latter, with the Iron Age settlement acting as a starting point for Roman operations to greatly ramp up. 

'The opportunity to carefully examine a site such as Blackgrounds, and map out a long history of the site, brought to life through artefacts, building remains and roads, has enabled us to provide a more in-depth understanding of what life was like in rural south Northamptonshire in the Iron and Roman Age,' said Mike Court, lead archaeologist for HS2. 

The history of the site, from the Iron Age to the Roman era, features in the new BBC Digging for Britain series, hosted by Professor Alice Roberts.

The episode featuring the Blackgrounds dig will air on BBC Two today, January 11, at 8pm.

HS2 COSTS SOARED ANOTHER £1.7 BILLION IN PAST YEAR DUE TO COVID - WITH TOTAL BUDGET SWELLING TO £106 BILLION 

The cost of the controversial HS2 high-speed rail project has increased by a further £1.7billion over the past year due to social distancing measures and work suspensions caused by the pandemic.

Coronavirus and lockdown restrictions first imposed in March last year disrupted work at most HS2 sites, causing further delays which have put even more strain on the UK's biggest infrastructure project.

Similar pressures have been reported by industry experts in projects ranging from Crossrail and the A303 Stonehenge tunnel to the Tideway tunnel and the Hinkley Point C nuclear power plant in Somerset.

As a result of work suspensions, social distancing measures, and reduced productivity over this year, costs have soared by around £1.7billion - another increase on the project's estimated £106billion budget.

Opposition to the project is mounting, with local anger contributing to the Tory by-election defeat in Chesham and Amersham. The new line is due to run through the Buckinghamshire constituency. 

The costs associated with Phase 1 of the line between London and Birmingham have increased by as much as £800million, people close to the project told the FT. 

That increase follows an £800million rise announced by HS2 in October, including money spent on remediating the terminus site at Euston in London. 

The price of the Birmingham Interchange station also rose by £100million to £370million even before contractors have been appointed.  

One contractor close to the project said that HS2 Ltd, the state-funded body responsible for delivering the line, 'doesn't really know how much Covid has added'. HS2 Ltd declined to comment when approached by MailOnline.  

Construction started on Phase 1 of the London to Birmingham line in August last year after more than a decade of planning. But the ballooning costs could add to Treasury fears that HS2 will be a black hole for taxpayers. 

The Department for Transport conceded to MailOnline that there had been 'unavoidable costs' arising from the coronavirus pandemic.
