Shalbon Bihar, Mainamati an isolated ridge of low hills in the eastern margins of deltaic Bangladesh, about 8 km to the west of Comilla town is a very familiar name in our cultural heritage, where archaeological excavations have revealed very significant materials. A landmark of our ancient history, it represents a small mass of quasi-lateritic old alluvium. The ridge, set in the vast expanse of the fertile lower Meghna basin, extends for about 17 km north-south from Mainamati village on the Gumti River to Chandi Mura near the Lalmai railway station. In its widest parts, the ridge is about 4.5 km across and its highest peaks attain a height of about 45 metres. These highlands were once thickly wooded with an abundance of wild life, but modern developments have rudely disturbed its serene and idyllic setting.
The twin names – Lalmai- Mainamati – of the place have significant link with the past: Lalmai or the southern part is identical with Lalambi-vana of the Chandra epigraphs, while the northern part recalls the name of the legendary Chandra queen ‘Maynamati’, mentioned in local ballads and folk-songs. The archaeological finds have now established beyond any doubt that the cultural and political centre of ancient Vanga-Samatata (southeast Bengal) was located here. The glory and magnitude of that remarkable past is emphatically manifest in the innumerable monuments, mounds and excavated remains, adequately supplemented by an impressive array of stray finds from the area.
The Discovery During the course of rebuilding the old axial road through these hills in 1875, workers accidentally uncovered the ruins of what at that time was thought to be ‘a small brick fort’. It was actually a Buddhist monastery. Some 72 years earlier (1803), from the same area, was discovered the first Mainamati relic, the copperplate of Ranavankamalla Harikaladeva, dated 1220 AD, which records a description of the capital city of Pattikera as ‘adorned with forts and monasteries’. The name now survives in the modern Patikara pargana of the locality.
