Heritage Open Day: St John Maddermarket Church in the heart of Norwich Lanes is a 500-year old city church with explosive history! Under the care of the Churches Conservation Trust, this church is squeezed ingeniously into a cramped site. St John's is rather oddly proportioned, being almost as wide as it is long. It is believed that an original chancel may have been demolished as part of a road-widening scheme when Queen Elizabeth I came to visit Norwich. It survived a gas explosion in 1876 during a choir practice that stunned the rector, singed the choirboys and shattered windows and furniture.
Today's sumptuous stained-glass windows are Victorian and twentieth-century replacements and the close set windows in the upper level flood the church with light.
