Ancient Persians built the first true arch bridges
Ancient Persians revolutionized civil engineering by systematically applying true arch structures to bridge building, enabling vast empires and influencing future architectural marvels.
The ancient Persians, during the Achaemenid Empire (550-330 BCE), pioneered the systematic use of true arch structures for bridges. Unlike earlier flat designs, these precisely cut stone arches efficiently distributed weight, creating stronger, more durable spans over rivers and valleys. This engineering marvel supported the 2,500-kilometer Royal Road, vital for trade and military movement across their vast empire.
