When walking inside the Roman Forum, there is always chance to see, beyond the arch of Septimius Severus, a paved area that is dark gray color. On the Via Sacra, before the entrance to the Roman senate, a small staircase takes the visitors in a subterranean area. This place is currently called the tomb of Romulus, but indeed it's a sanctuary dedicated to Vulcan, the god of the craftsmen. In the same place, a stone is carved with the oldest inscription in Latin language ,warning the visitors to not violate that sacred place. According to Livy, two are the accounts related to the death of Romulus: he may have been killed by the senators outside of the senate exactly in the place called later on Volcanal, or in the campus Martius when parading his troops. A lightning shrouded him and took him off the ground forever.
