Sonargaon is not a single ruin but a historic landscape in Narayanganj District, about 25 kilometres east of Dhaka, where political history, river trade and craft traditions overlap. The Foundation describes Sonargaon as an administrative and cultural centre of Bengal for roughly three centuries, from the Sultanate era through the period of the Baro-Bhuiyans. Its setting near waterways helped connect the region to trade and governance.
The old English-language listing in this database reduced that layered history to a short summary and made broad claims about a muslin hinterland. The more useful account begins with what local institutions document: Sonargaon was a major centre in eastern Bengal, associated with rulers, artisans and the production and exchange of fine muslin. The Foundation’s own historical pages connect its importance to the Bengal sultans and to Isa Khan, a leading figure among the Baro-Bhuiyans. These references place the town within regional history without suggesting that every surviving building belongs to one period or that all textile production took place at a single site.
