The Grand Anaicut Dam - Oldest In The World, This Dam Exemplifies The Amazing Engineering Marvels Of Tamilan

The Grand Anicut, also known as the Kallanai, is an ancient dam in Tamil Nadu state of south India. The Grand Anicut is the most ancient surviving irrigation work in Kaveri river delta. It is attributed to the Chola king Karikalan, and dates back to the 2nd century. It is considered the oldest water-diversion structure in the world still in use.
A poet sings
“Karikaalan kattivaithaan kallanai”


The sangam literature Pattinappaalai sung by uruthirang kannanar was solely sung in praise of Karikaal chola. It has no mention of Kallanai. We only understand that he strengthened the banks of cauvery.
Thiruttani and Velanjeri Copper Plates
Parantaka's plate is dated 932 A.D. It gives the names of the progenitors of the Chola line beginning with Vishnu, followed by Brahma, Marichi, Kasyapa, Surya and Usinara. Karikala, Sibi and Koccengannan.
KarikalaThree important events in the life of Karikala are mentioned.
(1) He caused the crest of the Cholas marked on the slopes of Himalayas.
(2) He raised embankments on either side of river Kaveri and controlled its flood
(3) He made Kanchi a city of palaces.


Udayendram plates
Parantaka Chola's Udayendram plates mention only the name of Karikala without referring to his exploits.

Hence Thiruttani and Velanjeri Copper Plates are perhaps the earliest Chola record to refer to the exploits of Karikala. Even though his conquests and building Kanchi palaces are as debatable let us see only Kallanai now.

The copper plates which mention Karikala as one of the ancestors of Cholas do not mention anything about Kallanai. Usually it is customary to record the grandest achievements of their ancestors (Sibi- sparrow, Manu needhi - chariot etc)

One more inscription throws a different light about uruthirang kannanar A mandapa was donated to kannanar by Karikala . Around 1200 AD Sundara pandiyan ransacked the whole of chola kingdom. He destroyed all forts, palaces etc. but left this one single mandapa untouched! There is a detailed inscription in thiruvellarai - in the form of a Tamil poem – which records this. Though it was a chola who donated the gift, it was a gift for a Tamil poet - uruthirang kannanar - that's all pandiyan considered!

The dam though very old has a strong foundation and a solid structure. It is still in excellent condition and is used as a major irrigation dam in Tamil Nadu. The dam has also been an inspiration for many recent modern day dams due to its amazing engineering. Due to its impressive architecture, the dam attracts a lot of tourists every year.

The dam is made of unhewn stone and is 1,080 feet long and 60 feet wide, across the main stream of the Cauvery.  The area is irrigated by the ancient irrigation network of which the dam was the centrepiece, covering about 69,000 acres. By the early 20th century, the irrigated area had increased to about 1,000,000 acres.
