Ancient Roman graveyard of...olive oil.9:23 PM
Most local residents don’t know what’s underneath the grass, dust, and scattering of trees. Monte Testaccio looks like a big hill, and in Rome people are accustomed to hills. In fact it's the biggest ancient roman rubbish dump.
For more than 250 years the ancient Romans methodically piled up broken terracotta amphorae, or oil jars, creating Monte Testaccio. Also known as Monte dei Cocci (literally meaning "Mount of Shards"), the mountain of jars is located right next to the ancient Tiber River port, and the Horrea Galbae warehouses, which would have been used to store imported goods like olive oil.'
As the oldest parts of Monte Testaccio are at the bottom of the mound, it is difficult to say with any certainty when it was first created. Deposits found by excavators have been dated to a period between approximately AD 140 to 250, but it is possible that dumping could have begun on the site as early as the 1st century BC.
