More of an ancient Roman city have been discovered by archaeologists.

The burnt remains of a 1,800-year-old kiln, use to create pottery, have been unearthed at Verulamium after essential work began to re-lay a gas pipe, giving archaeologists the opportunity to dig deep underground.

The team has also redrawn the map of the Roman city after making a series of discoveries including evidence of an expensive townhouse and the absence of a tower which would have sat in the corner of the city walls.

Simon West, District Archaeologist for St Albans City and District Council’s Museums team, said: “The pottery kiln is another exciting discovery that gives us a greater understanding of how Verulamium was set up.

“It is further evidence of just how advanced and productive the Romans who settled in Verulamium all those centuries ago were.

“The relaying of the gas pipe gave us a chance to discover new things about our past and we are certainly doing that.”

Councillor Annie Brewster, who leads on sport, leisure and heritage, said: “It is so exciting to discover additional details about the fascinating history of St Albans.

“To find another ancient pottery kiln is a wonderful surprise.”

Currently remains of Verulamium’s walls, defensive ditch and a central heating system of a Roman villa hypocaust can be viewed in the park, while the museum displays coffins with skeletons, mosaic floors and other items found following excavations in the 1930s.
