Bojjannakonda and Lingalakonda are two Buddhist rock-cut caves on adjacent hillocks, situated near a village called Sankaram, which is a few kilometres away from Anakapalle, Vishakhapatnam in the Indian state of Andhra Pradesh. The sites are believed to date between 4th and 9th Century A.D, when Buddhism is the majority religion of Sankaram (Sangharam as it was called then). The original name of Bojjannakonda is Buddina Konda.
Sankaram, a small village, is situated about a mile to the east of Anakapalli in the Visakhapatnam district of Andhra Pradesh. A short distance to the north of the village are two hills, the one on the east called Bojjannakonda and the other on the west called Lingalakonda, both of which are surrounded by paddy fields. 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 from the 4th to the 9th Century CE. The name of the village Sankaram is evidently a corruption of Sangharam (Boudha-arama, i.e., vihara) as these Buddhist establishments are generally known.
This is the eastern hill. It is 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.
It was excavated under the ages of Alexander Rim in 1906. Interesting aspect of this site is it feature all three phases of Buddhism i.e. Hinayana, Mahayana and Vajrayana.
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.
On this hill there are six rock-cut caves of which some have sculptured panels. One main cave has sixteen pillars, or which five are broken, and it enshrines a monolithic stupa in the centre. There is a pradakshina-patha around it. On the ceiling over the stupa is a carving of a chhatra, i.e., umbrella which was originally connected with the top of the stupa, the shaft being now lost. Above this cave, is an upper storey with the figures of Buddha. In all, on this hill [Bojjannakonda], there are six rock-cut caves of which some have sculptured panels. Most panels consists of a seated Buddha and attendants.
