Heritage Open Day: Join us for a talk that discusses the stained glass in the windows of the South Transept. Designed by Dunstan Powell in the early 1900s, these windows depict a wide variety of subjects, from the Old and New Testament, as well as from English history. Virtually all the windows you will see at the Catholic Cathedral of Saint John the Baptist, Norwich, were formed by one company, John Hardman & Co., between 1894 and 1910. During the nineteenth and twentieth centuries, Hardman & Co. was one of the leading makers of stained glass in the world. The Cathedral's windows were designed specifically for the Cathedral by John Hardman Powell and his son, Dunstan Powell, and constitute one of the finest collections of stained glass that you can find anywhere in the country.
