The Berici Hills stand out, south of Vicenza, with the shape of a parallelogram, whose major axis is oriented towards the Northeast.
The rocks, in most carbonatic, which consists of the backbone of the Colli Berici lead to attach to a marine hills.
It is assumed that the sequence of rock layers is the result of a slow and steady process of deposition of sand, mud and fragments of shells on the bottom of a sea.
The flora is characterized by berica thermophilous vegetation, the environment a hot climate, or microterme, usually live at altitudes well above.
This situation is due to the huge climate changes which has undergone the place over millions of years: in Ice Age is probably formed a flora microterma, approached a thermophilous vegetation in the immediately subsequent to a progressive warming of the globe.
