ARCHAEOLOGICAL discoveries are set to delay the completion of a £100million regeneration of Southampton city centre by months.

Construction work on the former Bargate Shopping Centre has helped unearth rare finds which will lead work over-running.

The finds from the excavation in Queensway, conducted by Southampton City Council Archaeology Unit, include a 14th century stone cannonball, a 15th century jar which once held liquid mercury, and a 17th century plate with a bare-breasted woman depicted on it.

As previously reported, the 400,000sqft scheme by Tellon Capital is set to include 24 retail and restaurant units, five retail pavilions and accommodation for 450 students, and show off stretches of the old city walls hidden by previous developments.

James Burchell, partner at developer Tellon Capital, said: “The archaeology has delayed the delivery of the Bargate but we believe it’s crucial we take our time to understand the history which, as you can see from the pictures, is really special.

“In the very short time, we’ve chosen to spend longer on careful extraction and preservation techniques – this history is priceless and we won’t rush it.

“We will keep everyone abreast of progress as we go.

“We’ve always appreciated the unique history associated with this site, but these three items are a fascinating example of the range of periods associated with this fantastic city.”

Dr Andy Russell, from Southampton City Council Archaeology Unit, said the excavation site will be around 2,000 square meters.

He added: “It is great to have the opportunity to look at this area. Southampton was the first town in England to use guns for its defence, and this stone cannonball is made of flint, which would shatter on impact and burst into hundreds of razor sharp splinters.

“We definitely expect to excavate more finds.”

The current finds were made at the end of January and the current archaeological dig in that area – which has since yielded some Roman pottery – will continue until mid- April.

Demolition work took place at the site in December 2017 and the scheme was originally expected to be completed by Christmas this year.

Councillor Satvir Kaur, cabinet member for homes and culture said: “It’s wonderful that these historical and cultural discoveries have been unearthed, and we look forward to seeing what else is uncovered.”

Councillor Daniel Fitzhenry, leader of the opposition Conservative group on the council, said: “As much as we would like to see the site developed, it is absolutely right to look into these finds further as they are a key part of our local history and culture.”
