The four clerestory windows in this Welsh Church have been filled with stained glass celebrating four Welsh Saints: St Non, St David, St Gwenffrewi and St Teilo.

Each window uses symbols inspired by the life and legends of its Saint:

• The planting and patronage of fruit trees by St Teilo and his riding of a stag to claim land;

• The plan of the Holy Well of St Gwenffrewi with symbols of her martyrdom,

• The stone arch of St Non’s Well in Pembrokeshire containing her Cross and the lightning that, legend has it, raged during the storm into which her son St David/Dewi Sant was born.

• Finally, St David’s window contains his classic symbol, the leek, as well as the earth mound that ‘arose’ to facilitate his preaching and a representation of St David’s Cathedral, site of extensive pilgrimage.
