Shalvan Vihara a tourist centre noted for antiquity. Salvan Vihara is among the most important excavated sites in mainamati. It lies about the middle of the Lalmai ridge in the vicinity of the present day bangladesh academy for rural development at Kotbari near Comilla. Excavations have exposed a large paharpur type Buddhist monastery and other material objects datable from the 7th to 12th centuries AD. Formally arranged in four wings around a central shrine, this 167.6m square monastery contains a total of 155 cells.
Its single entrance in the middle of the north wing is set in a grand 22.6m wide front facade with guardrooms projected outwards. All the walls of the monastery are solid and massive, the back wall being the most massive, 5m thick. This feature, together with the forbidding character of the single gateway with its guardrooms, and the dreary look of the massive outer wall, must have given it the appearance and utility of a citadel necessitated by the increasing wealth of these establishments and the insecurity of the period.
