Rome’s next luxury hotel has some very good bones: Archaeologists said Wednesday that the ruins of Nero’s Theater, an imperial theater referred to in ancient Roman texts but never found, have been discovered under the garden of a future Four Seasons Hotel steps from the Vatican.

Archaeologists have excavated deep under the walled garden of the Palazzo della Rovere since 2020 as part of planned renovations on the frescoed Renaissance building. The palazzo, which takes up a city block along the broad Via della Conciliazione leading to St. Peter’s Square, is home to an ancient Vatican chivalric order that leases the space to a hotel to raise money for Christians in the Holy Land.
