Why are roman ruins far beneath the ground?

Roman ruins are often found far beneath the ground due to centuries of urban development, natural sedimentation, and changes in land use. As cities grew, layers of debris, soil, and new constructions accumulated over time, burying older structures. Additionally, events such as earthquakes, floods, and the general decline of the Roman Empire led to the abandonment and subsequent entombment of these sites. Excavations reveal these buried ruins, providing insight into ancient Roman life and architecture.
