Found on the brink of war
In 1939, with World War II about to begin, archaeologists in Britain were excited by a discovery from 1,300 years ago.
Inside a grassy mound at Sutton Hoo, in Suffolk, they unearthed the remains of an Anglo-Saxon ship, possibly the tomb of a 7th-century nobelman.
The wooden ship had rotted away, but its outline, and some of the treasures buried with it remained. Among the gold, silver and iron was a sword, a shield and this warrior's helmet, probably the most famous of all Anglo-Saxon museum treasures.
A rare find
Made of iron, with decorated panels of bronze covered with tin, the Sutton Hoo helmet is a very rare find.
Only three other helmets of this age have been found in England.
It was made with great skill for a great man. Who was he? Probably a nobleman of the Angles, the Germanic people who settled in eastern England after the end of Roman rule in Britain.
No body was found in the ship-grave, but there are clues which tell us when it was buried.
The helmet was badly damaged, crushed when the wooden burial chamber collapsed with age and the weight of soil above.
Experts put together the fragments, to rebuild it, and also make a modern replica. How impressive it looks, with its face-mask with eye sockets, eyebrows and nose.
Each eyebrow ends in a boar's head, and between the eyebrows is a dragon-head.
Nose, eyebrows and dragon together make the shape of a bird with spreading wings.
Panels on the helmet are decorated with battle scenes and animals. One scene shows a man on a horse fighting a fallen enemy, another shows two warriors with swords and spears.
The burial ship was a wooden rowing boat, about 24 metres long, and probably old when it was buried (there are signs that it had been repaired).
Ship-burials are known from Sweden, and the helmet art looks Swedish too. So it's possible the East Anglian nobles had Swedish ancestors and family ties.
The gold coins came from the kingdom of the Franks (in continental Europe) , so it's clear that people during this early period of England's history travelled far and wide, from Scandinavia to the lands of the old Roman Empire.
