About Kallur Chola Tank (Kallur Eri) – Thanjavur Outlier
A 95-ha Chola-period eri (tank) at Kallur, 8 km south of Thanjavur, representing the smallest but best-preserved satellite of the Kaveri delta tank cascade feeding the Brihadeeswarar Temple hydraulic landscape. The tank is enclosed by a 2.2-km earthen bund 5 m high with laterite sluice head and 1.1-km anicut channel from the Vennar distributary, storing 1.2 Mm³. Dated to Rajaraja I phase (c.1010 CE) via Tamil Brahmi sluice inscription recording the eri's donation to the Brihadeeswara, the tank demonstrates Chola nagara–temple hydraulic management alongside the earlier Kallanai Grand Anicut. The bund incorporates medieval flood memory via sluice marks.
Why it mattersBest-preserved temple-tank outlier illustrating Chola hydraulic urbanism alongside Kallanai.
