The Guild of Corpus Christi was founded in 1343, one of the city’s richest religious groups who gathered for social and charitable activities before they were closed at the Reformation. They built the guildhall for their meetings and the stained glass dates from about 1500.

But some of the panes show graffiti from the 19th century and can be found throughout the building. I like the primitive skull and crossbones. The one on the left says Glazer I think.
