Biblical archaeology of Rome
The Biblical archaeology of Rome illustrates a number of important archaeological sites of Biblical significance that can help to substantiate the historicity of the Bible. Although perhaps better known for its ancient monuments, such as the Colosseum, Trevi Fountain, and the Spanish steps, there are numerous sites of Biblical importance in Rome including Mamertine Prison, the Church of Saint Paul Outside the Walls, Saint Peter’s Basilica and Square, and the Arch of Titus. 
Arch of Titus
The Arch of Titus, built in 81 A.D., is an arch that can be found near the Colosseum and the Roman forum. It was built to celebrate Titus’s capture of Jerusalem. The arch features many reliefs, a couple of which that are of Biblical significance. One shows Roman soldiers carrying away the Menorah and other loot from the temple. The other shows the procession of Titus and the Roman soldiers after concurring Jerusalem. The destruction of Jerusalem was prophesied first by Daniel and then by Jesus. 
One of the reliefs previously mentioned, the one of Roman soldiers carrying the menorah away from the temple in Jerusalem, is of great significance. This relief is the only known image of the temple menorah. The menorah, which was originally painted gold, meets the requirement for the temple menorah laid out in Exodus 25: 31-40. Because the relief is one of the only known images of the menorah, it is used as a reference for images of the menorah found today, including the Emblem of the State of Israel.
Mamertine Prison is a prison in the Roman Forum. Not only did it house many prisoners, but it is also thought to be the place where Paul and Peter were imprisoned. If this is true, then it is the place where Paul wrote Ephesians, Philippians, Colossians, and Philemon, subsequently converting many people, including his guards.
Mamertine Prison held both Peter and Paul in their final days. Nero ordered that Paul be beheaded. His remains were put where the Church of St. Paul Outside the Walls now stands. Peter requested that he be crucified upside down so as not to outshine Christ. He was granted his wish in 64, A.D. in what is now St. Peter's square in Vatican City. Mamertine Prison was used as a church around the 8th century, with frescoes found inside dating back to as early as the 6th century. In the 17th century, St. Joseph of the Carpenters was built on top of the prison, where it still stands today.
Churches in Rome
St. Peter's Basilica
St. Peter's Basilica, built from 1506 to 1615, is significant in many ways. It is one of the largest church buildings in the world and it is where the Pope preaches. It is also the site of Peter's tomb. At the end of his life, Peter was imprisoned in Mamertine Prison. In 64, A.D., he was sentenced to death by crucifixion. However, he requested that he be crucified upside down so as not to outshine Christ. His request was approved, and they crucified him upside down in what is now St. Peter's square in the Vatican city. He was the buried in a small grave on the Vatican Hill. Over the years, the grave evolved into a small shrine. After about three hundred years, Constantine ordered that a church should be built on the site. 
Basilica of Saint Paul Outside the Walls
The Basilica of Saint Paul Outside the Walls is located just outside the the wall that guarded Ancient Rome. It was founded by Constantine in the 4th century A.D., and is one of the four Papal Basilicas, the others being the Archbasilica of St. John Lateran, the Basilica di Santa Maria Maggiore, and the previously mentioned St. Peter’s Basilica. The church is most famously the site of Paul's tomb. Paul arrived in Rome, specifically at Mamertine Prison, in 61, A.D., where he awaited his death. After about four years of imprisonment, Nero ordered that he be beheaded. He was buried in a Roman tomb about two miles from where he was killed. His tombstone reads PAULO APOSTOLO MART, which translates to Apostle Paul, Martyr. The site was a place of worship until Constantine declared a church be built on the site.
