Modern archaeology and history reject this as the location of the Tarpeian Rock on a number of grounds both topographical and historical. Coarelli and the vast majority of experts put it on the Arx overlooking the lower Forum, probably somewhere in the area above the Carcer. Alas, whether it was there, or here, or somewhere else, landslides and general wear and tear and decay have long since completely erased the actual location: in our terms, the 'actual' location of the Tarpeian Rock is now hanging somewhere in the air.
