Bojjannakonda and Lingalakonda are two Buddhist sites which exist on adjacent hillocks near a village called Sankaram. It is located at about 45 km from Vishakhapatnam and just a few kilometers from Anakapalle. The sites are believed to date between 4th and 9th Century A.D, that was when at Sanakaram (Sangharam as it was called then) when the 3 phases of Buddhism (Hinayana, Mahayana, and Vajrayana) flourished.
Sankaram, a small village, is situated about a mile to the east of Anakapalli in the Visakhapatnam district of Andhra Pradesh. Within a short distance to the north of the village are two hills, one on the east called Bojjannakonda and the other on the west called Lingalakonda both surrounded by paddy fields. Both the hills contain numerous monolithic stupas, rock-cut caves, chaityas and monasteries forming one of the most remarkable Buddhist establishments in Andhra Pradesh during the period of 4th to 9th Century CE. The name of the village Sankaram is evidently a corruption of Sangharama(Boudha-arama) as these Buddhist establishments are generally known.
This is the eastern hill covered with a large group of monolithic stupas surrounding the rock-cut platforms of the Maha stupa The dome of the stupa is found constructed of brick. Groups of rock-cut and brick stupas and small chaityas surround this stupa. In two of the brick stupas, stone relic caskets in the form of miniature stupas were found. There is also a stone [Linga being the name locally applied to the stupa].
An Image of the Goddess Hariti is found at the foot of the hill as per the archaeological sources. In all, on this hill [Bojjannakonda], there are six rock-cut caves of which some have sculptured panels. In general, each panel consists of a seated Buddha and attendants. There are also Terraced Chaitya Griha's present towards North of the Maha Stupa. These form the monastery for the Buddhist monks.
The western hill is known as Lingalakonda is covered with a large number of rock-cut small stupas form the shape of a ridge. Numerous antiquities were recovered during the excavations conducted by Mr. Alexander Rea in 1907-08 on both the hills. During Excavations From this area pottery, coins of gold, copper and lead; seals, terracotta inscribed tablets, terracotta beads, and terracotta figures, One gold coin, Some copper coins and only one lead coin were recovered as per the archaeological sources.
As Buddhism began to spread, many learning centres and aramas for the monks were set up in various regions. They can also be seen at Thotlakonda, Bavikonda, Pavurallakonda around Vishakhapatnam. They all flourished around 3rd century BCE to 3rd century CE, but then gradually faded out, probably due to the revival of Hinduism.
