The first Rebuilding Act, passed in 1669, stipulated that the better to preserve the memory of this dreadful visitation, a column of either brass or stone should be set up on Fish Street Hill, on or near the site of Farynor's bakery, where the fire began. Christopher Wren, as surveyor-general of the King's Works, was asked to submit a design. Wren worked with Robert Hooke on the design. It is impossible to disentangle the collaboration between Hooke and Wren, but Hooke's drawings of possible designs for the column still exist, with Wren's signature on them indicating his approval of the drawings rather than their authorship. It was not until 1671 that the City Council approved the design, and it took six years to complete the 202 ft column. It was two more years before the inscription (which had been left to Wren — or to Wren's choice — to decide upon) was set in place.
