Determining the actual age of Sarsuna as an inhabited locality is a matter on which comprehensive research is required. From fragmentary ancient evidence, it appears that the term ‘Basin Saluno’ appeared in a map prepared by Ptolemy (Claudius Ptolemy, 100-170): the great Greek historian and cartographer. Dinesh Chandra Sen in one of his research works speculated that “salsuno” mentioned in Ptolemy’s map is the locality presently named Sarsuna. There are further references to this obviously ancient and historically important locality in Bengali literature. Pratap Chandra Ghosh’s (1845-1921) novel ‘Bangadhip Parajay’ (1869, 1884), based on the lives and times of Pratapaditya, Basanta Roy and Kedar Roy, and is set in Roygarh-Sarsuna.

Before becoming a part of the city of ‘Calcutta’, Behala had its own significant status. Job Charnok acquired the lease for three villages for building a fort and settlement in the name of the East India Company from Sabarna Roy Chowdhury the landlord(zamindar) residing in Barisha (Behala). The site of the present General Post Office (centrally located in Kolkata’s business district) was originally occupied by Sabarna Roy Chowdhury’s Kachari (court and office). The controversy about who should be regarded as the founder of Kolkata – Job Charnok or Lakshmikanta Chowdhury (a member of Saborno Roychaudhury’s family) indicates that this family from Sarsuna, Behala played a significant role in the narrative surrounding the foundation of Kolkata.
