The area began to be developed in the industrial revolution. The land was laid out for housing, as a residential square, in 1832, taking its name from the local landowner, the Marquess of Northampton. The gardens were opened to the public in 1885, with funding from the Metropolitan Public Gardens Association. The Association's landscape gardener Fanny Wilkinson designed the gardens, and included a drinking fountain and bandstand, both of which remain, as does a circle of London plane trees. The fountain in the square commemorates the 1885 restoration of the gardens by Shropshire magistrate Charles Walker, who had been born in Clerkenwell. Lady Margaret Georgiana Graham, daughter of William Compton, 4th Marquess of Northampton, opened the restored gardens on 8 July 1885.
