Lalitgiri
Cuttack district, India
Lalitagiri (Odia) (also known as Nalitagiri) is a major Buddhist complex in the Cuttack district in the Indian state of Odisha. The complex is home to stupas, 'esoteric' Buddha images, and monasteries (viharas), which is the oldest site in the region. Significant finds at this complex include Buddha's relics. Tantric Buddhism was practiced at this site. Together with the Ratnagiri and Udayagiri sites a short distance away, Lalitagiri is part of the "Diamond Triangle" of Buddhist sites. It used to be thought that one or all of these were the large Pushpagiri Vihara known from ancient records, but this has now convincingly located at a different site.
