The Aqueduct of Jerwan is an ancient water supply system located in modern-day Iraq. Built during the reign of the Assyrian king Sennacherib in the 7th century BCE, it was designed to transport water from the Khosr River to the city of Nineveh. The aqueduct is notable for its impressive engineering, featuring a series of arches and channels that allowed water to flow over long distances. This aqueduct is considered one of the earliest examples of large-scale hydraulic engineering. Its construction demonstrated the advanced skills of the Assyrians in managing water resources, which were crucial for agriculture and urban development in the arid region. Today, the Aqueduct of Jerwan remains a significant archaeological site, reflecting the ingenuity of ancient civilizations.
