Discover Budalur: Grand Anicut and Cauvery

Near Budalur lies Grand Anicut, also known as Kallanai. The ancient dam stretches across the Cauvery and is made of rough stone and clay. It is attributed to Karikala Chola and is said to have been built about 2,000 years ago. For a stay in Budalur, this distinctive structure in the surrounding area offers a focus on the history of water management.

Stone construction and water distribution

Grand Anicut is 329 metres long and 20 metres wide. Its purpose was to divert water from the Cauvery for irrigation in the fertile Thanjavur delta region. The water flows into an interconnected network of canals and supplies agricultural land. The structure includes sluice gates that regulate the water flow. Rice fields lie in the surrounding area. Water management has been a cornerstone of agriculture here for centuries.

The construction is attributed to Karikala Cholan in the 2nd century AD. He had flood embankments built to irrigate land alongside the river. The solid mass of uncut stone and clay is a characteristic feature of the ancient structure. Kallanai and Grand Anicut refer to the same dam.

River landscape and park

Green fields and the river are part of the landscape around Grand Anicut. Shady trees grow in nearby Anaicut Park, which offers views of the dam and river. If you plan to take a break there, check in advance what visitor access is currently available. Follow local guidance while exploring and stay on designated paths.
