 It is from Avellino and is linked by a mountain road to the ski resort of Laceno.The town's name appears for the first time in a donation dated 883, with which the Lombard prince Sichard granted the abbess of S. Sofia a property located in "Lions" (Lioni).The ancient settlement was probably one of the smaller neighboring towns of Ferentino, a Samnite stronghold destroyed by the Romans during the wars between these two peoples.
