Chakzam or Chagzam itself means an iron bridge in Tibetan language and it could mean any one of the hundreds of iron bridges in the Himalayan regions of India, Tibet, Bhutan and Nepal. However, we refer to the bridge in Tawang District as ‘the’ Chagzam bridge as this one is an ancient, centuries old, special iron bridge.

Exploring the Chagzam Bridge Tawang, an experience of a lifetime

Oh, how time flies! I can still vividly recall the day we visited the Chakzam Bridge, nestled in the breathtakingly beautiful Arunachal Pradesh, about 25 km from the Tawang Monastery. It was quite a journey, taking us over an hour and a quarter, although the distance as the crow flies was only 7.5 km! But the winding mountain roads made it seem like an eternity. The road was good for most part leading to unmetalled, gravel road for the last few kilometers. Here is the complete guide to explore the iron bridge.

Before we hit the gravel road, we passed by a quaint little village called Shernup. There were flowers of many hue blooming on both sides of the road. Our friend it was called the Cosmos Flowers (Scientific name – Cosmos bipinnatus) or the Mexican Aster. The local youngsters often call it “I Love You” flowers. Probably the Monpa boys woo Monpa girls with these flowers! 🙂 🙂 We made a mental note to stop here on our way back.

Sange, our friend, said it was still not the season. During season, the fields and sides of hills are full of these pretty flowers. At Chug valley near Dirang, Ziro valley and many other valleys, these pop up magically.

As we got down from our vehicle we were greeted by the faint sound of river flowing nearby. It was indeed music to our ears. We were then directed to collect the keys to the bridge from the house of the village elder (Sarpanch). It was quite surprising to learn that the bridge was locked!

A few years back one of the villagers had noticed that some of the iron chain links from the bridge were found missing, probably stolen. These fetch a lot of money in the black market because of its historical value, so some thieves might have stolen the same for a quick buck. To prevent further pilferage, the bridge -was shuttered and locked.

We climbed down the steps on the side of the river bank and soon we could hear the river crashing against the rocks in a huge roar and soon we got our first view of the magnificent historic Chagzam Bridge Tawang. I had goosebumps, just imagining how this engineering marvel was accomplished 600 years ago, perhaps from the year 1420 to Year 1430 AD.

We passed a short structure with a bunch of prayer stones, which may have held a few prayer wheels as was the norm in those days. You can see prayer wheels almost everywhere in Arunachal Pradesh. The housing wall had some stone inscriptions in Tibetan which we could not decipher. Chakzam bridge is about 60 Metres including the housings at both the ends. The iron chain links start at the beginning of the housing.

Excitement was building when we opened the lock and threw open the shutter. The 8-metre long housing or the rooms were neither too big nor impressive. It was purely functional. But what lay beyond them was what we had come to see. And there it was, the Chakzam Bridge in all its glory!

There it was. At first Chakzam bridge looked like a combination of bamboo, cane, straw and rattan bridge, the entire length of which was covered with long strips woven to form a kind of a mat. The bridge was swaying due to the wind. There were the ubiquitous prayer flags, strung along the length, fluttering noisily. These flags have Buddhist mantras printed on them and serve to protect the bridge.

At the first instance it did not look safe at all. No one wanted to step on the weak looking bamboo bridge. All the travelers around me were suddenly extremely polite saying ‘you first’ (pehle aap). 🙂 haha. On a closer look I could make out the steel chains and thick wire mesh peeking through gaps in the mat. My thoughts were “Wasn’t some chain links stolen from this bridge?” 🙂 , but I couldn’t resist the urge to cross it.

I opted to go first. Gingerly I stepped on to the bridge. My feet sank a bit and so did my heart! I took few more steps a bit more boldly now. It was not easy to walk as the bridge was like a hammock and the bottom was quite narrow, just enough for one foot at a time!

Soon I got the hang of it and walked length of the bridge to the other side which was also shuttered and probably locked. I even lay down on this huge ‘hammock’. The bridge was about 40 M above the river and when I looked down at the flowing river from the center, it had a dizzying effect on me.

The Chagzam Bridge offers stunning views of the surrounding mountains and valleys. I am sure in winter these mountain peaks would snow capped. The view from the bridge is truly breathtaking and is a sight that you won’t forget. 

As we made our way back, I couldn’t help but feel a sense of nostalgia, remembering the good old days when bridges like Chakzam were a symbol of human ingenuity and perseverance. Chagzam bridge Tawang may not be very long but its construction is a feat of engineering that will leave you in awe.

Construction of the Chakzam Bridge Tawang

The History

The Chagzam Bridge is a suspension bridge located in Tawang, Arunachal Pradesh. It was built in the year 1420 AD by Thangtong Gyalpo (tangton gyalpo), a Buddhist monk and a renowned architect of his time. Chagzam bridge spanning over Tawang chu river, is almost 600 years old, making it the oldest bridge in Tawang region.

The bridge played a significant role in the history of Tawang, connecting the two important villages, Kitpi on the North and Mukto at South of Tawang River, facilitating travel and trade. This bridge apparently reduced the distance by many tens of kilometers! Despite facing numerous natural calamities and political turmoil, the bridge has stood strong and continues to be a symbol of resilience and endurance. It remains an awe-inspiring sight, reminding us of the power of human ingenuity and the importance of preserving our history.

The sides are similarly woven. The wire mesh perhaps is comparatively a new addition.

The bridge has had regular maintenance and reinforcements made over the years to ensure that it’s stable and safe to walk over.

The Unique Design and Engineering Challenges Faced During Construction of Chakzam Bridge in Tawang

The construction of the Chakzam Bridge in Tawang posed unique design and engineering challenges that required innovative solutions and unwavering determination. For finances and resources, Lama Thangtong Gyalpo (Tangton Gyalpo), created dance and music forms to be performed in various villages. The people were educated about the usefulness of the bridge. Money so collected was used for the bridge. Many people from surrounding villages agreed to work on the Chakzam bridge.

The harsh terrain, extreme weather conditions, and limited accessibility made the construction of this bridge a formidable task. However, Thangtong Gyalpo and builders involved in the project overcame these challenges with their perseverance, skill, and ingenuity. The completion of the Chaksam Bridge stands as a testament to the human spirit’s ability to conquer seemingly insurmountable obstacles. It serves as an inspiration to all those who face difficult challenges in their lives, reminding us that with hard work and dedication, anything is possible.

The Chagzam Bridge Tawang is an engineering marvel that has withstood the test of time. It is made of iron chains and bamboo, cane, rattan and straw and is suspended over the Tawang River. The bridge is 60 meters long and about 2 meters wide (at the west part), making it one of the unique suspension bridges of its time. The bridge, either by design or otherwise, has withstood strong winds and earthquakes, and it has survived many natural disasters over the centuries!

There are two iron chains at the bottom and a pair of iron chains on either side. Layers of bamboo mats are placed on it so that one can easily walk.

The Builder, the Architect, the Man – Lama Thangtong Gyalpo

Thangtong Gyalpo (Also spelt as Tangtong or Thang Tong), was a legendary figure in the history of Tibet and Bhutan and was said to be a disciple of the very first Dalai Lama. He was born in the 14th century in Tibet and spent most of his life traveling across the Himalayas, building bridges and monasteries, and spreading Buddhism. Tangtong Gyalpo was not only a great architect but also a spiritual leader and a social reformer. He is credited with introducing the art of iron chain bridge construction in Tibet and Bhutan, which revolutionized transportation in the region.

Thangtong Gyalpo was not only an architect but also a physician, a blacksmith, and a poet. He was a prolific builder. He is known for building 58 (some believe he built more than 100) iron-chain suspension bridges across Tibet, Bhutan, and India. The Chagzam Bridge is one of his most famous creations. Due to this reason he was fondly called Chakzampa (Iron Bridge Maker).

He is also credited with building many important Stupas with progressive designs, which are now in the Tibet and Bhutan region including Jangtsa Dumtseg Lhakhang in Paro, Bhutan.

Thangtong Gyalpo (Tangton Gyalpo) is also known for his founding of Ache Lhamo or Tibetan opera, which is a type of masked cham dance. This was then performed at various villages to raise resources to build bridges. I guess he must have been the most enterprising person of his era!

The Impact of Chagzam Bridge on the local community and Tourism

The Chakzam Bridge has had a significant impact on the local community and tourism in Tawang Arunachal Pradesh. The bridge has made it easier for locals to travel between villages and access essential services such as healthcare and education.

We totally recommend staying at homestays, like we did. We interacted with the family so much that at the end of our stay we got quite emotional and I am sure I saw a few pairs of moist eyes. We stayed in a homestay called “Pal-Mo homestay” very close to the Tawang Monastery.
