A Hypothesis of a Lost State Infrastructure System in Historic Cities

This work presents an original interdisciplinary conceptual hypothesis proposing that a significant portion of underground and above-ground structures in historic cities may represent remnants of a former state-level infrastructure system. The study integrates systems engineering logic, urban studies, hydrology, architectural analysis, and acoustic signaling mechanisms within known physical principles.
