This blog showcases the new cancellation, covers posted on the first day, and travel tips for those wishing to visit the dam and the post office.
The Story Behind Kallanai Dam
For readers who may be new to this site, here’s Kallanai Dam history in English. The Kallanai is one of the oldest water-diversion structures in the world. It was originally built around the 2nd century CE.
So, who built Kallanai Dam? It was constructed by the Chola King Karikalan to regulate the flow of the Kaveri River and improve irrigation in the region.
Today, the dam is not just an engineering wonder but also a heritage symbol that connects culture, history, and livelihood. It continues to serve farmers even after nearly 1,800 years.
The dam is located in Thanjavur district, 15 km from Tiruchirapalli and 45 km from Thanjavur.
