Medieval Palace Excavation Unveils Historic Papal Residence in Rome

Archaeologists in Rome have unearthed remains of a medieval palace that served as a papal residence before the Vatican. Located outside the Archbasilica of St John Lateran, this significant discovery comes ahead of the 2025 Catholic Holy Year. The site includes walls from the Patriarchio, a basilica envisioned by Emperor Constantine.

Archaeologists have made a groundbreaking discovery in Rome, unearthing the remnants of a medieval palace that once housed popes before the Vatican became their official residence. This significant find was made during pre-renovation excavations for the 2025 Catholic Holy Year, commonly known as the Jubilee.

The excavation took place in the square outside the Archbasilica of St John Lateran, revealing a complex architectural structure. The uncovered walls are believed to have protected the Patriarchio, a monumental basilica originally planned by Emperor Constantine in the 4th century, according to a statement by the Italian Culture Ministry.

'This is an extraordinarily important find for the city of Rome and its medieval history, as no extensive archaeological excavations have ever been carried out in the square in modern times,' the ministry noted. The building's initial structure, dating back to Constantine's era following his declaration of tolerance for Christianity in 313, was expanded over centuries and served as the papal residence until 1305 when the papacy temporarily moved to Avignon, France.
