Self-guided Sightseeing Tour #20 in Rome, Italy

Monte Testaccio or Monte Testaceo, also known as Monte dei Cocci, is an artificial mound in Rome composed almost entirely of testae, fragments of broken ancient Roman pottery, nearly all discarded amphorae dating from the time of the Roman Empire, some of which were labelled with tituli picti. It is one of the largest spoil heaps found anywhere in the ancient world, covering an area of 2 hectares at its base and with a volume of approximately 580,000 cubic metres (760,000 cu yd), containing the remains of an estimated 53 million amphorae. It has a circumference of nearly a kilometre (0.6 mi) and stands 35 metres (115 ft) high, though it was probably considerably higher in ancient times. It stands a short distance away from the east bank of the River Tiber, near the Horrea Galbae where the state-controlled reserve of olive oil was stored in the late 2nd century AD. The mound later had both religious and military significance.

The Non-Catholic Cemetery, also referred to as the Protestant Cemetery or the English Cemetery, is a private cemetery in the rione of Testaccio in Rome. It is near Porta San Paolo and adjacent to the Pyramid of Cestius, a small-scale Egyptian-style pyramid built between 18 and 12 BCE as a tomb and later incorporated into the section of the Aurelian Walls that borders the cemetery. It has Mediterranean cypress, pomegranate and other trees, and a grassy meadow. It is the final resting place of non-Catholics including but not exclusive to Protestants or British people. The earliest known burial is that of a Dr Arthur, a Protestant medical doctor hailing from Edinburgh, in 1716. The English poets John Keats and Percy Bysshe Shelley, as well as Russian painter Karl Briullov and Italian Marxist Antonio Gramsci are buried there.

The pyramid of Cestius is an ancient Roman pyramid in Rome, Italy, near the Porta San Paolo and the Protestant Cemetery. It was built in the style of the Nubian pyramids as a tomb for Gaius Cestius, a member of the Epulones religious corporation. It stands at a fork between two ancient roads, the Via Ostiensis and another road that ran west to the Tiber along the approximate line of the modern Via Marmorata. Due to its incorporation into the city's fortifications, it is today one of the best-preserved ancient buildings in Rome.
