No other parish church in the land has retained a complete set of late medieval glass but thankfully Fairford has. They date to around the 1400's and were used to express and teach the Christian faith.
Perhaps the most striking elements of the windows are the 'Fairford Devils' These grotesque figures adorn many of the windows and the image shows Satan siting in hell devouring the damned!
