Mausoleums Z, Φ (phi), Χ (chi) and Ψ (Psi). In the period from the end of the 2nd Century to the middle of the 3rd Century, mausoleums were built along with various freestanding buildings. All buildings except Mausoleum R1 had their entrance to the south, in the direction of the circus and the Via Cornelia. The mausoleums had been used by many generations and shared by several families. Archaeologists found around 120 burials in Mausoleum F and at least 170 in Mausoleum H. An approximate calculation of the number of body and urn burials in the 22 excavated tombs yielded a number of more than 1,000 funerals. This large number is due to the high infant mortality and low life expectancy in the 2nd Century CE. The former owners of six mausoleums (A, C, H, L, N, and O) have been identified from inscriptions above the entrance door. Mausoleum N is an example of a mausoleum that was used by different families at the same time. The inscription reports that it is the mausoleum of Marcus Aebutius Charito, but that one half belongs to Lucius Volusius Successus and Volusia Megiste, who jointly purchased some of it. 21st century More of the necropolis was unearthed in 2003 during construction of a car park. The site is now open to visitors. Some tombs have undergone restorations, such as the ten-month project involving the Valerii Mausoleum. St. Peter's Grave (Field P) The field named P (Peter Campus) is the small area in which the suspected grave of the Apostle Peter is located. Peter was, according to tradition, after his martyrdom in the Circus Nero, buried here. Some 100 years after the death of Peter, a shrine was erected over his grave. This shrine is adjacent to the so-called Red Wall. Immediately adjacent to the suspected Peter grave, some other tombs were found. The arrangement of the graves suggests that the place of Peter's tomb was the site of some early veneration. The shrine, also called the "Trophy of Gaius", is named for the theologian Gaius of Rome who lived in Rome during the time of Pope Zephyrinus (198–217 CE). Consider this quote from Eusebius of Caesarea: The Greek term used by Gaius——usually means a monument or a trophy of victory. Eusebius interpreted the quote 100 years later as an indication of honorific graves. On the right side of the "Trophy of Gaius" is
