The Corbridge Treasure is a Treasure mainly of iron artifacts which was excavated in 1964 at the Roman site of Coria , near what is now Corbridge, Northumberland, England (not to be confused with the gold coin hoard found nearby in 1911).
It came from the central row of administrative buildings in one of the earlier forts underlying the later Roman city, and probably dates from between 122 and 138 AD.
The contents (which included iron/steel, copper alloy, lead alloy, stone, glass and organic objects) were buried in an iron-clad leather chest made of alder planks joined together with dovetails at the corners.
The most famous objects inside were the six upper and six lower halves of the "lorica segmentata" armor, which, although not identical, may have been just three whole cuirasses or elements of twelve partial sets. It was this discovery that allowed Charles Daniels and H. Russell Robinson to understand how this type of armor should be reconstructed. Prior to the discovery of the Treasure, "people knew that segmented armor existed, but we did not know how it was assembled or how it was made."
The Corbridge Treasure also contained bundles of spearheads, still bound with rope; artillery bolts; a sword scabbard; various tools and implements (including a block pulley and a Crusie lamp ); objects related to carpentry, such as nails and carpentry dogs ; a small wooden bucket or mug. There were also fragmentary remnants of feathers (possibly cushion padding or helmet plumes), wax tablets for writing and (almost the only case in Roman Britain ) fragments of papyrus.
All of the organic components in the treasure (including the box itself) were preserved by the mineralization caused by the rusting of its iron and steel contents.
The treasure has been variously interpreted as material hastily concealed from barbarian attack.
