The Architecture of Historic Isfahan (Esfahan)
Shahrestan bridge is probably the oldest bridge in Isfahan. It is said that the foundations of the bridge go as far back as the 3rd to 7th century. It spans about 110 meters and is just over five meters wide.
The bridge has two curves in its structure. One is the parabolic vertical arching of the span making the middle the highest point. The second parabolic curve is horizontal, offering the bridge more strength against the flow of the water. The road on the bridge has a gate as shown below.
