Chittapur town has its own historic background of Nagavelambika Temple and Hajarat Chittavali shaha Darga.

These edicts were written in the Prakrit language and Brahmi script and one of them was used as foundation of the pedestal for the Kali idol.

Clay pendants of Roman origin, black polished pottery, Shatavahana and pre-Shatavahana coins, ornaments made of copper, ivory and iron, a township with paved pathways, houses, and limestone flooring have been found.
