Sutton Hoo

In 1939, just before the outbreak of the second World War, an archaeologist named Basil Brown excavated the largest of 18 burial mounds in the grounds of a country house at Sutton Hoo (Eastern England) 

Inside he discovered a spectacular undisturbed burial in a vast ship.

The burial dated to the earlyAD 600s, when Sutton Hoo belonged to the Anglo-Saxon kingdom of East Anglia. 

The extraordinarily rich grave goods suggested  that the ship burial commemorated a very high-ranking man, possibly even a king.

Jacobs had found a piece of iron and immediately stopped the work and carefully explored the area... and uncovered five rivets in position on what turned out to be the extreme end prow, or stern, of a ship.He realised this was no ordinary burial.
The 27-metre-long ship had been dragged up a steep slope from the River Deben to the burial ground above. Over time, its wooden oak planks and ribs decayed, replaced by compacted sand. This left a clear impression of the hull in the ground, studded with iron rivets. The Sutton Hoo ship is the biggest and most complete Anglo-Saxon ship ever found, and is longer than many of the largest modern ocean-going yachts.The ship and its contents remained hidden for more than 1000 years, until they were revealed again in the summer of 1939. Although boat and ship burials are known from Scandinavia and mainland Europe, they are extremely rare in Anglo-Saxon England. The Sutton Hoo ship burial is the richest ever discovered in Britain. 

The Sutton Hoo helmet is the most iconic object to survive from Anglo-Saxon England. It is decorated with pictures of warriors and powerful animals.
The helmet was made of iron and probably weighed about 2.5 kg. It had a leather lining and holes under the nose for the wearer to breathe
