Thor's hammer part of Viking finds returning to Thetford

The Thor's hammer pendant, which could have been worn by one of the invaders, was found just outside South Lopham, about 11 miles (17km) from Thetford

A Thor's hammer and a pottery lamp are among Viking Great Army finds returning to the town where they were discovered.

Thousands of Scandinavians formed an army in England to raid and conquer between AD865-878, and Thetford in Norfolk was one of their winter camps.

The story of how this led to the town becoming a major Viking settlement will be told at its Ancient House Museum.

Curator Oliver Bone said the exhibits "show how important this area was in the Viking story".

The Anglo-Saxon Chronicle recounted how the Great Army raided, conquered and wintered in England, until it was defeated by Alfred the Great at Edington in AD878.

Exhibits on display include a tiny (4cm or 1.5in) Thor's hammer, found at South Lopham.

• Anglo-Saxon kings mostly vegetarian, study finds

• Largest hoard of gold Anglo-Saxon coins unearthed

• Roman treasure returns to town where it was found

Mr Bone said: "It's a little pendant that would have been worn around the neck that probably had a protective function - if you were part of the Viking Great Army you probably wanted the god Thor on your side."

The hoard of King Edmund pennies was discovered at Worlington in Suffolk, about 14 miles (22km) south west of Thetford

A "rare hoard" of King Edmund pennies will also be included, which was either hidden by Anglo-Saxons as the Vikings approached or loot lost by the raiders.

Mr Bone said: "When the Vikings came to East Anglia in AD865, the East Anglians made peace with them and gave them horses.

"But when they returned to overwinter at Thetford in AD869, they fought and killed King Edmund."

Excavations have revealed Thetford had a number of Viking-era pottery kilns, where this lamp was found

He was canonised shortly afterwards and his body laid to rest at Bury St Edmunds in Suffolk.

"The interesting thing for our area is the development of the memorial coinage to St Edmund, within 10 to 15 years after and it seems to be part of the Christianisation of Viking settlers," Mr Bone said.

"The melding of the Scandinavian and Anglo-Saxon cultures is the stimulus for Thetford's development into a trading and craft-making centre, particularly into the next century."

Other finds on display include a Viking sword and brooches found just outside Thetford (on loan from the British Museum) and a Viking-raid era gold plaque of St John the Evangelist discovered at Brandon.

The exhibition, called The Vikings, history on your doorstep, opens on Saturday, 16 July.

The Viking-era hoard found at Hingham, Norfolk, might also have been hidden in the wake of the raiders' arrival
