A flask that may have held a future king's urine will be among the artefacts on display when the extraordinary haul of a long-lost shipwreck is exhibited in Norwich.

Later this month, items discovered aboard the sunken HMS Gloucester will be made public for the first time - 15 years after its discovery and more than 340 years after the ship went down.

Eastern Daily Press:

Ahead of the historic exhibition, at Norwich Castle, fresh details of what artefacts will be included have been revealed.

Among these are a brass trumpet mouthpiece, a leather pouch embossed with the crown symbols and a urine flask which may have been used by the future King James II.

Eastern Daily Press:

The artefacts were found on the seabed by brothers Julian and Lincoln Barnwell - who had long since searched for the ship's remains.

Their remarkable discovery came in 2007, with the pair then periodically bringing more and more items to the surface.

The exhibition will be the first time the public has been able to lay eyes on them.

Eastern Daily Press:

Dubbed Norfolk's Mary Rose, the 17th century warship sank off the coast of Great Yarmouth on May 6, 1682 - while carrying the then Duke of York.

The future king was saved as the ship sank, but up to 250 people died in the tragedy.

The Wroxham brothers, said: "The discovery of the Gloucester has been an incredible adventure and we feel very honoured that this important part of history is being told in such a professional and detailed manner.

"The Norfolk Museums Service and UEA have done real justice to the Gloucester and all the people on board, some of whom sadly lost their lives in the tragedy."

The Last Voyage of the Gloucester: Norfolk's Royal Shipwreck, runs from Saturday, February 25 until Sunday, September 10.
