It is not known why the Roman temples were built on the site, but there are examples elsewhere of the Romans building on the site of Iron Age temples or shrines. However, it is more difficult to argue for this being the case at Chanctonbury Ring, given the gap of half a millennium between the hill fort's abandonment and reoccupation. In other locations, such as at Hayling Island and Maiden Castle, there was continuity of religious use between Iron Age and Roman times, which was clearly not the case with Chanctonbury.
