The Persian Qanat

The Persian Qanat (Inscribed)

The Persian Qanat by Bernard Joseph Esposo Guerrero

This is probably the UNESCO World Heritage Site I spent the most time in trying to understand how to “properly” visit it during my recent trip in Iran. When I was just about to give up on it, a sign suddenly emerged in the streets of the historic city of Yazd referring to the “Zarch Qanat gallery”. This seems to be an improvement since the previous reviewer went to Yazd last year (exactly 12 months apart!), reporting the glaring lack of any public information about the qanats.

Later on, my friend and I realized that there were in fact a lot of signs all over showing some sort of a direction. Only to find out that — after intently and passionately following the signs for nearly an hour — it was not really leading us to a “gallery” (i.e., an exhibit, a museum, or a showroom)! Rather, it was just illustrating where the qanat flows underneath the city! This finding was interesting, but it was far from constituting a “proper” visit.

Much to my surprise later that day, however, we eventually got the proper visit that we needed no less than inside the Great Friday Mosque itself. At the main gate of the mosque, I already wondered why there was a banner congratulating “… the successful inscription of the Persian Qanats as a UNESCO World Heritage Site”. Sadly, it obviously and shamefully fails to indicate the more important detail – that a part of the qanat can actually be accessed within it. Inside, there is a small opening on the ground that can easily be missed which leads to a payab (underground water chamber). This payab, which has been supplying the mosque the water it needs since it was erected, is one of the public openings of the Zarch qanat. The properly lit stairway goes down to some 30 meters below the ground until one reaches the well.

Surprisingly, during our two hour wandering inside the complex, despite the hoards of tourists visiting the mosque and the no lack of tourist guides around, we only saw two other curious visitors who took the effort to go down the site, and they probably were not even aware of what it is at all. Even in the walking city tour we hopped on the following day, our guide never mentioned anything about the qanats and their importance. We also learned later on that the Zarch qanat runs as well under the Emir Chaqmaq complex, but going there proved futile – there is no way to “see” the qanat.

In one of those cosy coffee shops in the city, I had a talk with its owner whom I shared my sense of achievement and pride in seeing a part of the Zarch qanat with when I least expected it. He then enthusiastically showed us a ground cover in front of his shop, opened it, and explained that it’s one of the shafts of Zarch. It was quite deep and one can hear well the flowing water!

He also told us about the ancient watermill of Koushk-e No in the neighbhorhood which is also being repaired (or prepared) at the moment to become a tourist showroom for the qanat. Furthermore, he advised that if we go there, and if we’re lucky, we might just have a peek inside. And we eventually did.

Going down through its small opening, several layers of water channels and chambers were seen. Apparently, the site lies at the crossroad of three different qanats, with the Zarch qanat specifically powering the mill. It is also interesting to know that the temperature on the ground compared to the temperature down where the waters flow can differ from 17 to 20 degrees Celsius, making it a wonderful refuge from the heat outside.

The Zarch qanat has been supplying most of the water requirements of the desert city of Yazd for more than 3,000 years already. It also happens to be the longest qanat in Iran at 120 kilometers in length. In its entire course, from the mother well (water source) to the farmlands it irrigates, more than 2,000 shafts have been constructed. Indeed, qanats are a proof that ancient Persians were masters in hydraulic engineering.

The Zarch qanat definitely plays a strong role in the nomination of the Historic City of Yazd, which also has a living tradition registered in the Masterpieces of Oral and Intangible Heritage of Humanity, as a UNESCO World Heritage Site in its own right. This proposal will be decided upon this coming June when the committee convenes in Krakow, Poland. I sincerely wish Yazd the best of luck.

****P.S. Albeit not among the World Heritage-listed properties, other qanats we saw in the trip include the Solomon’s spring, an exit point of a qanat that feeds water to the Fin Garden, a UNESCO World Heritage Persian Garden, and the 7,000 years old Sialk Tepe, the remains of the oldest known ziggurat, in Kashan; and the qanat that supplies water to an ancient caravanserai, refrigerator, and ice house in historic Maybod, another desert city along the Silk Road that is also in Iran’s present Tentative List for UNESCO WHS listing.
