The travertine (sedimentary stone) altar with a Latin inscription that revealed it to be a sacred shrine to Apollo was discovered near the monumental entrance of the sanctuary.
What followed was another discovery, an altar dedicated to the Roman goddess of fortune and luck, Fortuna Primigenia . The only other previously discovered sanctuary to the goddess was discovered in Palestrina, just south of Rome, which is a popular heritage site.
Another altar was discovered that was dedicated to the divine mother goddess of ancient Egypt, Isis.
Finally, a marble statue of Hygeia, deity of health and daughter of Asclepius, the healing god, was discovered at the site.
