Sankaram:

A Britisher Alexander Rea unearthed Sankaram, a 2000-year-old Buddhist Heritage site in 1907. Located 40 km from South of Vizag, locally it is known as Bojjannakonda. The three phases of Buddhism viz. Hinayana, Mahayana & Vajrayana flourished here. This complex is famous for its numerous Monolithic Votive Stupas, Rock cut caves, and brick build structural edifices. Excavations yielded several historic potteries, Satavahana coins dating back to the 1st century A.D. several clay tablets bearing figures of Buddha etc.
Bojjannakonda, the Eastern one bears richer architecture of the two hills. It presents a picturesque appearance with its Main Stupa on the hilltop and dominating myriads of stupas, mostly rock-cut and rarely brick-built, one above the other. Almost every outcrop and protuberance has been converted boldly into a stupa. Similarly at Lingalakonda, there are innumerable rock-cut monolithic stupas in rows spread all over the hill. Other Attractions are a Maha stupa nearby which yielded a relic casket, 3 chaitya halls, votive platforms, stupas and vajrayana sculptures. A gold coin of Samudragupta dating to 4th century AD was also found at this place. The Vihara was active for about 1000 years, spanning the Theravada, Mahayana and Vajrayana phases of Buddhism. This place offers a glimpse into the rich Buddhist heritage and culture is a must see for any tourist.
