A section of Roman road, part of one of the most important roads built in Roman times, has been unearthed beneath Old Kent Road in south-east London.
The 2,000-year-old road, known as Watling Street, was part of a route from the ancient Roman port at Dover through London to the West Midlands.
Regarded as one of the most crucial Roman roads in Britain, this unexpected discovery was made during excavation work carried out by Southwark Council and the utility company Veolia, aimed at installing a low-carbon heating network.
Constructed shortly after the Roman invasion of Britain in 43 AD, it has proven quite challenging for archaeologists to identify the exact path it took, despite the fact that Roman roads are typically straight.
“In the planning stages of this project, we anticipated addressing this issue, but the remarkable preservation of the road is surprising. We hope this initiative will help resolve other archaeological inquiries within the borough,” stated Dr. Chris Constable, the in-house archaeology officer for Southwark Council, in an interview with BBC.
The road was uncovered by a group of archaeologists from the Museum of London Archaeology (MOLA), with Dr. Constable offering essential guidance and support.
According to Southwark Council, this discovery provides the first tangible evidence that portions of the road still exist directly beneath its contemporary equivalent, the Old Kent Road.
The well-preserved road segment, which is located south of the intersection of Old Kent Road and Ilderton Road, is roughly 19 feet (5.8 meters) wide by nearly 5 feet (1.4 meters) high.
Southwark Council said distinct layers could be seen and showed a solid foundation of compacted gravel sealed by two layers of chalk, before it was topped with another layer of compacted sand and gravel.
The original surface of the road would likely have been made from the same material and sat at a similar level to the modern road, but this has been lost, says Southwark Council. The base of the modern road was built directly on the Roman fabric.
Gillian King, director of archaeology at RPS Consulting Ltd, described the discovery as “a key finding for archaeological research for London”.Archaeological-themed apparel
“The discovery of an intact section of Roman Wating Street directly under the current Old Kent Road has redrawn the Roman road map for Southwark and informs on Roman construction techniques generally,” she said.
Dave Taylor, MOLA’s project manager, said: “It’s amazing this section of road has survived for almost 2,000 years.”
He added: “There has been so much activity here over the past few hundred years, from sewers to power cables, tramlines and of course the building of the modern road, so we’re really excited to find such a substantial chunk of Roman material remaining.”
The discovery will be marked by a sign on the nearby Old Kent Road bridge. Find out more about the renewal of Old Kent Road at oldkentroad.org.uk
