According to Brian the shrine would have contained a sacred bell and almost certainly belonged to a saint or other holy person.
The artefact's intricate metalwork depicts a figure of the crucified Christ. His eyes are made from pale blue glass beads and he is wearing a three-pointed crown.
Panels at the front and back have small shamrock-shaped devices that are pierced with rivets to hold the device together and a cross would originally have been attached to it.
Other discoveries made at the site, which is believed to have been occupied from the ninth to the thirteenth century, indicate that it was of high status and of local military significance. As well as a large quantity of pottery, archaeologists found an iron arrowhead, an iron spearhead and butchered animal and fish bones.
Philip Maguire, Principle Information Officer at the DoE explained just how rare such an object actually is.
"There are only eight of these in Ireland, but the rest have been handed down, so this is the first time it has been found on a dig."
Although the shrine is currently the property of the landowner, it is hoped that in due course it will be acquired by Ulster Museum.
