The short history of Si-o-se Pol

This bridge that was built by “Allah Verdikhan oundiladze Gorji”, the famous Sardar of Shah Abbas, has a stable construction and some believe that because Allah Verdikhan was from the race of Georgians and the alphabet of Georgian has 33 letters, call this bridge Siose Pol, but this claim is totally failed because at first, this bridge has 40 apertures.

The main plan of Isfahan city in the time of Shah Abbas was “Chahar Bagh” which consisted of two axes that were perpendicular to each other. Si-o-se Pol was located along with one of these main axes for connecting the Chahar Bagh Abbasi to the Chahar Bagh Bala, Hezar Jarib garden, Abbas Abad and the neighbourhood of Jolfa.

The history of the establishment of Siose Pol and ambiguities in the history

There were written different years for the construction of Siose Pol in various books. at the time of holding the festival of Golrizan in the presence of shah Abbas in the year 1018, this bridge existed but the year of completion of the works of the bridge is different in various resources.

For example, in the book of “Alam Araye Abbasi” in the Safavid history, there was written about this bridge in the events of 1011 A.H and by the time of the establishment of this dynasty until the death of the First Shah Abbas, so this bridge existed on that time. it can be concluded that on the basis of the book of Alam Ara, the bridge was built in the year of 1011 A.H.

Si-o-se Pol in pahlavi

“Mirza Hassan Khan Jaberi Ansari” in the history of Isfahan and Rey, in the part of the events related to the year 1005 A.H. had pointed to this bridge in the description of Isfahan and he also wrote about the events of the year 1008:

“Shah came from Harat to Isfahan and completed the design of mansions and gardens that each of the top brasses built a garden with his own desire in the commentary of old Chahar Bagh in the Chahar Baghe Bala.”

And says in the following:

“Shah Abbas returned to Isfahan, commanded to the Allah Verdi Khan to build the bridge of Zayandeh Rood with the Divani mansion.”

He writes such a thing about the events of 1012:

“The great construction of door head of Eysariye and the excellent tiling of it… “

Jaber Ansari was also pointed to the construction of a bridge in his writing, in the year of 1011 A.H, but in some of his writing, knew this date as the time of exportation of the instruction of it and totally, there are some contradictions in his writing.

Based on the poetry of “Naghi Komrei”, the building of the bridge of Amir, if it is that bridge, it was done on the year of 1005 A.H. that the starting of construction of it should be in the year of 1003 A.H, to finish in the 1005 A.H.

Mirza Alinaghi Komrei, one of the poets of the Shah Abbas period, composed some verses about this bridge:  

“Falak ghadr Allah va yardi ke ghadr ze Abbas shah andar ayyam yaft

Bamdad big vierdi dadgar poli kedar aghaz va anjam yaft

Basee molk sirate agha Hossein bekheir alamal Hassan etmam yaft

Be daste zebar dast saab amir cho band amir in bana nam yaft

Pey sal tarikh in pol nayaft kasi khoubtar az pol etmam yaft”

An important point about the construction of Si-o-se Pol

Because the construction of the building of Abbas Abad was on one side of the Zayandeh Rood, so there should be a bridge for making connections at that time and in the year of 1005 A.H., so the presence of bridge is approved in the year 1005.

On the other hand, Allah Verdikhan that was the agent of constructing the bridge, in the year 1004 on the behalf of the first Shah Abbas was attributed to the Fars state and occupied to the management of the affairs of that region, so the reconstruction and improvement of this city and constructing of the Siose Pol should take place after the date of dispatching Allah Vedikhan and after the year of 1004 A.H.

In one of the historical documents, it is also written that in the year of 1005 A.H., the construction of the Allah Verdikhan bridge and improvement of Chahar Bagh street was finished and the theatres of passion- plays of Chahar Bagh were built in 1011 A.H. and all the buildings were finished in the year of 1025.

For answers to the ambiguities of the history of the establishment of the bridge, we should say that at first, Allah Verdikhan finished the building of the downstairs of the bridge in the year 1005 and in the year 1011 was became the agent of completion of the bridge and constructing the upstairs to in case of overflowing of the Zayandeh Rood, don’t make any disturbance in the traffic.

The Nowrouz festival in Si O Se Pol

The Nowrouz festival that was continued to three up to seven days, sometimes held with the command of Shah Abbas on the top bridge and the Golrizan festival took place and many flowers were poured on the way of king and his companions.

In the year 1018 that Farvardin festival was within coincidence with the month of Muharram, the Nowrouz ceremony was held for seven days and nights with the command of the king and made pouring the flowers (Golrizan) over the bridge and the because of the stunting of the people of Isfahan in decorating and ornamentation, the amount of 500 Toman of taxation of that year was forgiven by the command of the king.

At first.

The architect of Si-O-Se-Pol

The architect of Siose Pol was professor “Hossein Bana Isfahani” and his boy, “Mohammad Reza Isfahani” was also built the “Sheikh Lotf Allah” mosque. usually, the bridges are built in the narrow parts, but for building this bridge, Professor Hossein Bana Isfahani selected the widest part of the Zayandeh Rood, because this part of the river was created in the shallow, vast and calm bed.

Three kinds of materials were used for constructing the Siose Pol: for the bottom parts, the stone is being used and for the upper parts, bricks and Sarooj mortar and plaster. this bridge was built in a way that increases its moisture, durability and strength and water can’t harm it in a long time.

The architecture of Siose Pol

The traditional architect of Sio Seh Pol:

There are covered arcades on both sides of the bridge that from one side is afforded a view of the river and from the other side to the middle of the bridge and caused the making of the narrow, roofed passageway in both sides of the bridge.

The sidewalk of the bridge has also 99 niches that some paintings were there, but today there is no sign of them. the statue of Reza Shah is also existing in the front of this bridge and on the pillar with a height of 5 meters that today, this statue is located in the square of 14th of Esfand.

The arches of the bridge have pillars with a height of 7 to 9 meters that are so strong. in the 13th century, the entrance to the portal of the bridge was possible from the paved highway and there were 3 alleys in the three different levels. at first, this bridge had 360 meters’ length and 40 springs (big arch), but today it has 33 apertures and 14 meters’ width and also has 259 meters’ length.

In the northeast of the bridge, there is a brick-made building that was built with the remembrance of the tomb of Kamal Aldin Esmaeil and the mentioned street is called by the name of that honourable man that has an extension to the Jouni and Khajoo bridge.

In the past, this bridge had 6 alleys, but today it has only 2 alleys of sidewalk that one of them is on the above that its roof is sky and other is in the beneath that is roofed and it was made in the central pillars of the bridge and with a low distance of the river bed.

The problems of Si-O-Se-Pol

Siose pol was in the list of Iran’s national works on the date of 15th of Dey 1310 with the registration number of 110. the excavation of the subway’s tunnel and the sequential drying of Zayandeh Rood, caused this pretty bridge of the Safavid period to get cracking. of course, droughts and subsidences of Isfahan are also caused that Siose Pol and all of the Safavid bridges that were on the Zayandeh Rood, were subject to subsidence.

Si-O-Se-Pol is the only bridge that is not built on the stone floor and it is built upon the sandy floor. for this reason, the Safavids piled under the bases of the bridge with 30 meters’ depth. therefore, the life of this bridge depends to the water and when the water didn’t reach its mortar, the pillars are cracking and the bridge subsidences.

One of the reasons for today’s crackings of Siose pol is the movement of heavy cars on it that the passing the cars on the Siose pol got stopped after the revolution.

Why 33 Pol?

There are many theories about the number 33 that one of them is pointing to the relation of the race of Georgian of Allah Verdi Khan and the Georgian alphabet which has 33 letters. some totally rejected this theory, because at first, Siose Pol had 40 apertures.

Lord George Nathaniel Curzon” the british politician and Iran expert, says such a sentence about that:

“The human doesn’t’ have any expect to travel to Iran for seeing what can call it the bridge of the world.”

“Pietro Della Valle” also describes Siose pol in this way:

“There is a bridge on this river that is entirely made with bricks and its width is more than all of the bridges of Rome and its length at least 3 or 4 times bigger than those bridges.

the architecture of this bridge was done in a strange way and there are arcades in both sides of it that people pass from it’s beneath and above of it. the thing that attacts the attention more, is the corridors of the bridge that positioned almost at the same level and the whispering of water in the lower floor of bridge specially in the warm summer is so pleasant.”
