The construction of defensive walls in ancient times involved more than just erecting tall or thick barriers; it required addressing specific issues related to soil, water, and transportation in a constrained environment. This complex process was employed by Carthage when they embarked on building an advanced wall in Hispania, necessitating a deep understanding of the local terrain, precise measurements, and meticulous coordination among workers over extended periods. Such an approach mandated pre-planning regarding where to source dirt, how to move it, and at what point to convert it into usable bricks.

The start of the wall's construction did not occur on the city’s urban edge; rather, it began much earlier in the encompassing landscape and how it was utilized. This strategic planning sought to optimize resources and involve a systematic method for organizing labor. A thorough examination revealed that a significant portion of the construction materials was sourced from several kilometers away, indicating a well-conceived logistical network was necessary to transport materials efficiently to the site.

This geoarchaeological study provided insights into not only the methods of construction but also the socio-economic context of Carthage during the period. The findings shed light on the advanced techniques employed in ancient engineering, illustrating how innovative practices allowed Carthage to establish fortified positions in provinces such as Hispania, which were crucial for controlling territory and resources in the region.
