Geology

Fifty million years ago, the area of the Berici Hills was entirely submerged by water.
In this marine environment the Pietra Berica became a limestone of dual formation, clastic and biogenic, since it results both from the deposition of material transported from rivers to the sea, and from the sedimentation of skeletons of aquatic organisms as foraminifera and bivalves.

In those warm seas countless species of fish and clams lived, while the seabed was rich in corals and seaweeds.
The stone of the Berici Hills is also called soft stone, due to its easy workability and is classified into two distinct groups: the first one is called Pietra di Nanto and includes: the Nanto, the S. Germano, the Giallo Dorato, the Grigio Argento stone.
All these stones from the eocene, are dated to fifty-five million years ago and characterized by a straw-yellow or gray color, due to the presence of iron oxides in their chemical composition.
