The fountain was inspired by Demetrius Panioty, a member of the Panioty family who had moved to India from Greece as traders back in 1750. Panioty, who wrote for the Bengal Secretariat, later became Assistant Private Secretary to Governor General Ripon and several of his successors. In 1895, three years after his death, out of fondness for the man and his dedication to service, Lord Curzon had this marble drinking water fountain installed.
You can find this now dilapidated monument near Curzon Park Bus Stop, just opposite of Esplanade Mansion. You’ll have to hunt around the north-west corner of Surendra Nath Banerjee Park {now renamed as ‘Bhasha Uddyan’}. It’s complicated to find because it is surrounded by an unkept garden and is unidentifiable {there isn’t even a plaque for this heritage monument!}.
