Take the following as truth: The 27 b.c. triumphal arch (Arco d'Augusto), anachronistically ornamented with medieval battlements, stands at the junction of the imperial highways from ancient Via Flaminia and Via Emilia (which gave the region its name).
Then the following statement: "The battlements of the Arco d'Augusto are from the 1st century AD." is true, false, or inconclusive?
