An ancient helmet discovered below Coppergate in York will take pride of place in a new exhibition launched next month.

The Jorvik Story, an alternative to the Jorvik Viking Centre, which will be closed while a £4.8 million refurbishment is carried out, will tempt visitors to St Mary's Church, Coppergate, formerly the home of The York Story.

The Anglo-Saxon helmet, buried in the ninth century, will be part of a free exhibition, which will include a video presentation, which explains the history of the Viking Centre and looks forward to the creation of the new-look attraction, a Viking-age city.

A larger exhibition will show several buildings, which featured in the original Jorvik Viking Centre, and the popular Skullsplitter exhibition, which looks at the warrior traits of the historic settlers.

Richard Kemp, director of attractions for York Archaeological Trust, said: "Jorvik has become such an integral part of any visit to York that we wanted to ensure that visitors over the winter months would not be left disappointed when they could not get into the Jorvik Viking Centre.

The Jorvik Story is expected to open on November 13.
