Location
The Cholanadu region covers Central Tamil Nadu and East-Central Tamil Nadu. The region is sandwiched between the historical regions of Tondai Nadu in the north, the Madurai region in the south and Kongunadu in the west and roughly extends from Chidambaram in north to the southern frontier of the erstwhile Pudukkottai kingdom and from Tiruchirapalli in the west to the Bay of Bengal in the east.
According to the Gazetteer of the Trichinopoly District, Vol II, 1931, p 67, "the traditional meeting place of the three Tamil kingdoms was the temple of Cellānti Amman on the banks of the Kāvēri, twelve miles west of Kulittalai and three miles below the junction of the Amarāvati and the Kāvēri. The temple was the common place of worship for the kings of the three Tamil dynasties; a bund which runs to the south of the river marks the boundary between the Cōla and the Pāntya territories, and the Karaipōttanār on the opposite bank of the river was the boundary between the Cōla and the Cēra kingdoms".
