On the town's name, there is no unanimity of views: for some historians, it derives from the greek "larinos" (loud), while for others, it is linked to the Latin word "laridum" (lard). Another school of thought, finally, attests that it derives from the Etruscan word "lar" (head or principal). Municipality in the province of Campobasso, located at the stream Cigno, a tributary of the river Biferno, Larino is surrounded by green olive trees and a lush countryside. It is an active agricultural center with an important presence of well preserved artistic and archaeological evidence. The old town is rich in monuments of the Middle Ages and the Renaissance, such as: Palazzo Ducale, the watchtowers and the noble villas.
Former center of the Frentani, it was of great importance in the past, highly quoted by Cicero in his oration "Pro Cluentio. The fertile soil attracted the Romans, that have left here considerable traces of their presence. It was also the scenario of the battle between Hannibal and the Romans in 207 B.C. During the medieval period, Larino became a County and was frequently subject to looting and destruction. Hordes of Saracens and Hungarians reached the town, bringing death and destruction, and for these reasons the inhabitants were forced to move from the primary urban center to a better defensible site.
