ANSA.it reports on a Roman era brickworks in the town of Ronta that’s so intact it wouldn’t take much to restore it to working order.
The complex, which dates back to the 2nd century BC, is the second oldest brickworks uncovered in Emilia Romagna. An earlier structure in Ca Turci Cesenatico has been dated back to the end of the 3rd century BC, which was when the Roman first occupied the area.
Roman bricks were quite a bit thinner than modern ones, so Roman construction is pretty easy to spot.
After the fall of the Roman Empire, the art of brick manufacturing was lost in most of Europe, surviving only in Italy itself. Central Europe didn’t rediscover the skill until the 18th century and England until the 1100s.
