The earliest glass in the Cathedral dates back to the 1330s. During the Civil War of the 1640s, many of the windows were smashed, although the shards were retained and gradually reassembled.
Thankfully, the stained glass in the Presbytery was too high up to be easily destroyed and this remains a significant example of late-medieval glass painting and design.
However, much of the glass is corroded, resulting in a loss of the painted detail. In many places, the joints and surrounding stonework have also corroded and some of the glass segments have already fallen out.
We plan an extensive conservation programme which will restore the glass to its former colourful beauty
