The culture of the site reached its height in the early phase, 200 B.C, to A.D. 100 when a sophisticated bright-red polished ware appears in a variety of forms, with applied and incised decorative designs. In the late phase of the Period, A.D. 100-200, the glorious of the culture is obvious. It seemed to be a large city, which could have been governed under one ruler. The ancient population inhabiting the place was estimated to be 25,000. Archaeological Survey of India and University of California discovered the remains of a 2500 – year – old city at Sisupalgarh, situated on the outskirts of Bhubaneswar, Odisha on February 10, 2008.
