Mediæval churches in England and Wales (as across the British Isles and the Continent) were absolutely bursting with colour, with images of Our Lord, Our Lady, and the Saints of Heaven. These images were destroyed or painted-over at the time of the Protestant Reformation. The walls of parish churches and shrines were a veritable catechism in pictures.
St. Teilo’s Church in Wales has been restored so as to look as it did circa 1520. Layers of paint were removed to expose the original mediæval images.
