Dumfries Museum and Camera Obscura will become a bustling market on Saturday May 16.
Visitors will go back in time to see how ordinary Vikings dressed, lived, worked and fought.
There will be a special combat area and opportunities for children and adults to have a go at some of the crafts on show and sample some typical refreshments.
The event is part of a special weekend linked to the 2015 Scotland Festival of Museums.
The museum is also inviting over 18s to enjoy an entertaining evening in the company of some Viking raiders at the one-night only traditional Longhouse tavern.
There will be authentic drinks to purchase, Viking ‘lounge music’ and some unforgettable pub grub to try. Viking stories will be told and there’ll be games and crafts going on too.
Other events lined up over the weekend of May 15-17 include an illustrated talk by historic evironment records officer Andrew Nicholson on the excavation of the Galloway Viking Hoard, which contains precious objects from all over Europe.
It was discovered locally in 2014 and is arguably the most exciting ever found in Scotland.
Anyone who fancies trying their hand at treasure hunting will also enjoy the metal detecting session, led by Derek McLennan and Sharon McKee of Beyond the Beep.
The pair were involved in the discovery of the Galloway Hoard and are going to be sharing their love of metal dectecting with a real treasure hunt.
The festival is run by Museum Galleries Scotland and chief executive Joanne Orr said: “Festival of Museums is about igniting imaginations while celebrating Scotlandís wealth of culture. There is a packed programme this year with lots of extraordinary, surprising and exciting events over three fun-filled days.”
