During the summer, many churches are taking part in the Church of England promotion, encouraging visitors (and locals) to stop and look in more detail at the stained glass windows which are not only beautiful works of art, but in many cases tell something of the history of the church and its people. On social media, the search tag #stainedglasssummer will help you find churches locally that may be part of this.
For some churches in the Lyn Mission, I have added photos to the gallery, but this should be an incentive for you to get out and visit them yourself.
The link below will further explain what it is all about.
