the shrubs traditionally present at the emperors' estates.
Excavated below this location between the 3rd and 5th centuries CE, the Catacombs of the SS. Marcellino and Pietro house many tombs of very rich Christians who have left us wuonderful
frescoes recently restored to their original splendor through laser technology. With its 18,000 square meters of galleries and chambers at about 16 meters below
ground level, these catacombs represent an authentic tresure trove of Subterranean Christian Rome.
