There are two different theories about the origin of the name: one is about wine cellars and the other one about small monasteries.
According to the first one the name may derive from the wine cellars that were dug into the sandstone, which is really common in this geographical area. These cellars, called infernot, even though are not being used anymore they still exist nowadays and can be visited.
The other theory is about the small monasteries which in Italian are called Celle.[5]
The name appeared for the first time in a document signed by the Emperor Arrigo V in 1116.
