 The importance of the site of Ameno in prehistoric and protohistoric times is because of the fertile and healthy plateau that offers land suitable for crops and grazing.The area allowed the control of an passage, strategically placed between the lake and Agogna Valley.The lake was an easy link with Ossola and the Alpine passes; the Agogna valley was an active terrestrial itinerary from the most ancient prehistory, probably more suitable for the transhumance of the herds of animals from the Novara plain to the mountains rather than for the exchange of goods, which preferred instead the Ticino waterway.
