The 1034th Sathaya Vizha marking the birth anniversary of King Raja Raja Chola got underway here on last Tuesday (5th November) on the temple premises. Earliest Chola ruler Karikala Cholan in the early part of 2nd century built the world's first water diversion dam using mainly huge blocks of granite called ''Kallanai'' (Grand Anaicut) which is close to Tiruchi city. This way he prevented flooding during the monsoon season and diligently diverted the excess water for agricultural purpose in the delta region. That dam exists even to day as strong as ever and it is an engineering marvel. During the early British rule, British civil engineers in particular Sir Arthur Cotton used grand anaicut as a model and built the barrage across the Godavari river in Andhra state.
