Isfahan’s Famous Bridges
Isfahan, often referred to as “Half of the World,” is a city of wonders with breathtaking architecture, historical landmarks, and cultural heritage.

Si-o-Se Pol Bridge
Among the famous bridges of Isfahan, Si-o-Se-Pol stands out for its grandeur and historical significance. Built over the Zayandeh Rud River during the Safavid era (1602 AD), the bridge is named after Allahverdi Khan, a prominent commander of the time, and designed by the skilled architect Master Hossein Bana Isfahani. Unlike most bridges, which are built at narrow river points, this bridge was constructed at one of the river’s widest sections for its shallow bed and stunning views. Its name comes from its 33 arches, believed to be inspired by the 33 letters of the Georgian alphabet, reflecting Allahverdi Khan’s Georgian heritage.
Si-o-Se-Pol was once the lively center for water festivals during the Safavid period, with locals celebrating by sprinkling water and rosewater on one another. Walking across the bridge today, you can almost hear the echoes of those past celebrations. Made from a combination of stone, brick, lime mortar, and gypsum, the bridge is both beautiful and durable, though recent droughts have raised concerns about its foundations. With its original 40 arches reduced to 33 and a current length of 295 meters, it remains the longest bridge on the Zayandeh Rud. For a truly magical experience, visit at night when the bridge is beautifully lit, transforming it into a glowing masterpiece. Easily accessible from Si-o-Se-Pol Metro Station, this historic wonder invites all to enjoy its timeless charm.

Allahverdi Khan: The Founder of Si-o-se-pol
Allahverdi Khan (d. 1613) was a prominent military commander and statesman during the Safavid era under Shah Abbas I. Originally of Georgian origin, he rose to become one of the most trusted figures in Shah Abbas’s court and held the title of Commander-in-Chief of the Safavid Army. Allahverdi Khan is best known for commissioning the iconic Si-o-se-pol (Bridge of 33 Arches) in Isfahan, a masterpiece of Safavid architecture that served as both a functional bridge and a cultural gathering space. His contributions to Isfahan’s urban development cemented his legacy as a key figure in Iran’s history.

Khaju Bridge
Khaju Bridge, one of the most remarkable historical bridges of Isfahan, stands out for its elegant design and symmetry. Built during the reign of Shah Abbas II of the Safavid dynasty around 1650, this bridge was named after the Khaju neighborhood where it is located. It is also known by other names, such as Baba Rokneddin Bridge and Hassan Beik Bridge. The structure, spanning 133 meters with 24 arches, is celebrated for its exquisite tilework and was once considered one of the world’s most beautiful bridges. In addition to its architectural beauty, Khaju Bridge served a dual purpose as both a bridge and a dam across the Zayandeh Rud River.
At the heart of the bridge is the Shah Neshin pavilion, a royal viewing platform adorned with delicate paintings. This area was used by the Safavid nobility to watch swimming and boating competitions. On the eastern corners of the bridge stand two stone lion statues, believed by some to represent Bakhtiari guards of the Safavid era. Others see them simply as decorative elements. With wooden planks in its central section, Khaju Bridge controlled the river’s flow in a sophisticated manner for its time. Visiting Khaju Bridge today offers a unique experience—an opportunity to marvel at one of the finest examples of Safavid architecture while enjoying the serene natural beauty of Isfahan.

Shahrestan Bridge
The Shahrestan Bridge, located east of the city center, is the oldest of Isfahan’s historic bridges and a remarkable testament to Iran’s history. Its origins date back to the Sasanian Empire (1800 years ago), a period known for its influence on the Architectural Features of Ancient Persia, adding an aura of ancient majesty to the bridge’s design. Over the centuries, it was renovated during the Buyid and Seljuk dynasties, each era contributing to its evolving beauty and functionality.
Spanning 108 meters with a width of 5.2 meters, the Shahrestan Bridge showcases remarkable engineering. It features two carefully designed parabolas—the horizontal one strengthens the bridge’s foundation, while the vertical parabola centers its highest point for stability. The bridge’s thirteen pointed arches encase eight smaller arches, a strategic design that reduces water pressure and allows floodwaters to flow through efficiently. Situated near the Zayandeh Rud River and bordered by the distant Zagros Mountains, this bridge harmonizes nature and human ingenuity. As a symbol of Persian architectural mastery and resilience, the Shahrestan Bridge offers a captivating glimpse into Iran’s ancient engineering brilliance and historical depth.

Marnan Bridge of Isfahan
Marnan Bridge is a historical structure in west- Isfahan. It is believed by some archaeologists to date back to the Sassanian era, with significant renovations during the Safavid period. However, some historical texts suggest the bridge was built entirely during the Safavid era by an Armenian merchant named Sarfaraz, who funded its construction from his wealth. As a result, the bridge was also known as “Sarfaraz Bridge.” Today, there is a park and neighborhood named after it nearby. While the theory of its Sassanian origins is debated, its architectural style closely resembles Safavid bridges, leading many to believe that the renovations gave it its current appearance.
The Marnan Bridge stretches 160 meters and originally had more than its current 17 arches, some of which were sealed due to droughts and lower water levels. Smaller decorative arches are interspersed among the larger ones, and the varying widths of the bridge are clearly visible from a distance, with the central section being wider and now serving as a viewing area for visitors. The bridge’s stone foundations are strengthened with Sarooj mortar, while its body was built using bricks and gypsum mortar. Similar to Khaju Bridge, Marnan wasn’t just for transportation but also functioned as a dam, with farmers using it to irrigate nearby fields by closing the arches.
Sarooj: Ancient Mortar
Sarooj is a traditional mortar used extensively in ancient Iranian architecture, known for its durability and water resistance. It is made by mixing lime, clay, sand, ash, and sometimes animal fibers. In certain cases, egg whites were also added to enhance its binding strength and improve resistance to cracking and water penetration. This mortar played a crucial role in the construction of bridges in Isfahan, including Marnan Bridge, due to its ability to withstand moisture and temperature changes over time.
Sarooj’s water-repellent properties made it ideal for structures exposed to the elements. It was also used in yakhchals (Iranian ice house) to preserve stored ice during hot summers and in kabootar khanehs (pigeon towers of Iran) for their solid, lasting interiors. These innovative uses highlight the ingenuity of ancient Persian construction techniques and the rich architectural heritage of Iran.
