The Corbridge Treasure is a collection of primarily iron artifacts that was excavated in 1964 at the Roman site of Coria, near what is now Corbridge, Northumberland, England. This treasure should not be confused with a nearby gold coin hoard found in 1911.
The artifacts were discovered within the central row of administrative buildings in one of the earlier forts that underlie the later Roman city of Coria. The dating of the treasure is believed to be between 122 and 138 AD.
The contents of the treasure, which included items made of iron/steel, copper alloy, lead alloy, stone, glass, and organic materials, were found in an iron-clad leather chest constructed from alder planks joined together with dovetails at the corners.
One of the most prominent objects within the Corbridge Treasure was the discovery of six upper and six lower halves of the "lorica segmentata" armor. Although not identical, they may have constituted three complete cuirasses or parts of twelve partial sets. This find was instrumental in helping scholars like Charles Daniels and H. Russell Robinson understand how this type of armor was assembled and made. Prior to the discovery of the treasure, the existence of segmented armor was known, but its construction remained a mystery.
Additionally, the Corbridge Treasure 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 associated with carpentry like nails and carpentry dogs, as well as a small wooden bucket or mug. Fragments of feathers, possibly used for cushion padding or helmet plumes, wax tablets for writing, and rare fragments of papyrus were also found.
All the organic components in the treasure, including the leather chest, were preserved through mineralization caused by the rusting of the iron and steel contents.
Interpretations of the Corbridge Treasure vary, but it is often seen as material that was hastily concealed, possibly in response to a barbarian attack or other adverse circumstances, with the intention of later recovery.
