Persian Engineering refers to the advanced engineering practices developed in ancient Persia, particularly during the Achaemenid Empire (c. 550–330 BCE). This era is known for remarkable achievements in civil engineering, including the construction of extensive road networks, bridges, and irrigation systems that supported agriculture and trade. The Qanat system is a notable example of Persian engineering, consisting of underground aqueducts that transported water from mountainous regions to arid areas. This innovative method allowed for efficient water management, significantly contributing to the prosperity of Persian cities and agriculture, showcasing the ingenuity of ancient Persian engineers.
