St Magnus narrowly escaped destruction in 1633. A later edition of Stow's "Survey" records that "On the 13th day of February, between eleven and twelve at night, there happened in the house of one Briggs, a Needle-maker near St Magnus Church, at the North end of the Bridge, by the carelessness of a Maid-Servant setting a tub of hot sea-coal ashes under a pair of stairs, a sad and lamentable fire, which consumed all the buildings before eight of the clock the next morning, from the North end of the Bridge to the first vacancy on both sides, containing forty-two houses; water then being very scarce, the Thames being almost frozen over." Susannah Chambers "by her last will & testament bearing date 28th December 1640 gave the sum of Twenty-two shillings and Sixpence Yearly for a Sermon to be preached on the 12th day of February in every Year within the Church of Saint Magnus in commemoration of God's merciful preservation of the said Church of Saint Magnus from Ruin, by the late and terrible Fire on London Bridge. Likewise Annually to the Poor the sum of 17/6." The tradition of a "Fire Sermon" was revived on 12 February 2004, when the first preacher was the Rt Revd and Rt Hon Richard Chartres, Bishop of London.
