Artificial hill in the port area of ancient Rome, near the warehouses (horrea). From the Latin mons testaceus, commonly called “Monte dei Cocci”, consists of numerous layers of terracotta fragments of amphorae, used for the transport of goods, which were systematically discharged and accumulated after being emptied in the nearby river port, activity continued for about two centuries. The oil amphorae used by the intense trade with the regions bordering the Mediterranean Sea were no longer reusable, the problem of disposal was solved in this place, where the fragments were stacked with maximum economy.
