it was only in the past fortnight that the team realised the foundations were from a temple from the Roman era, the floor of which was scattered with broken pottery dating as far back as 800 BC.
Not sure what that means...Rome wasn’t founded until 753BC. Maybe they are saying it was a more ancient building adapted later as a Roman temple? It makes no sense the way its written....
Probably a typo, should be 80 BC.
The 800 BC pottery was pre-Roman, naturally. :’)
