The large number of altar stones found indicates that Ganventa was a major site for the worship of the goddess.
Focused searches in 1970, 1971, and 1974 resulted in the find of about 240 altars and statues, votive stones and remains of a Roman building.
The names of the persons who dedicated the statues and altars show that they were merchants from Italy, Cologne, Trier and Britain.
Other wares included ceramics from the area around the Rhine, terracotta figurines from Cologne and Trier, and wine from Southern France and the Mosel.
One inscription found translates to: "Before Nehalennia, Marcus Exingius Agricola, citizen of Trier, salt merchant in Cologne, has fulfilled his promise, willing and with reason."
