Temple of Saturn
It is certain that it was "hard by [under] the Temple of Saturn at the head of the Roman Forum", but its exact location is still unknown. Due to archaeological data from excavations by Kähler in 1959, which seem to confirm data from excavations by Bunsen in 1833, many scholars now believe that it was located at the southeast corner of the podium of the "Rostra Augusti" on a symmetrical axis with the "Umbilicus Urbis Romae".
