At some point in the fort’s life, one of the barrack blocks was converted into fabrica or workshops. Buildings were added to the barrack block in the north-west corner of the fort forming two new wings aligned with the rampart.
There is evidence for metal furnaces and industrial activities such as blacksmithing and weapon production in an extensive area of ash and clinker-filled pits. Archaeologists also found a fragment of sandstone flooring.
A Roman fort required engineers, carpenters, masons, wagon-makers, blacksmiths, painters and other artisans to function properly, so the soldiers turned their hands to these skills.
Archaeologists think that the buildings which stood here formed a Fabrica. During the excavation of the Lunt Fort, a large area of ash was found, indicating that this workshop may have been used for blacksmithing, as well as repair and manufacture of weapons and armour.
Armour was polished with a mixture of olive oil and pumice or sand to remove rust.
