Behind the cross wall in the western granary is another raised floor, set on to a mixed rubbled and concrete base and raise on stones. The floor is incredibly heavy, heavier than the original granary floor. Date - 5th -9th century.
Possible use through the 9th century?? That's astounding. I mean, seriously cool. I know Birdoswald lingered for maybe a hundred years after the Romans went bye-bye. But is there anything else on the Wall/Stanegate that shows life going on for possibly four centuries?
