Well Dressing is an ancient custom unique to Derbyshire. Each year, between May and September, hundreds of well dressings are created by volunteers in Derbyshire villages. According to many sources, it developed from a pagan tradition of making sacrifice to the Gods of wells and springs to ensure a continued supply of fresh water. In the Derbyshire tradition, pictures are made for the most part of individual flower petals pressed onto clay covered boards. In 2007, many wells were dressed to mark the bicentenary. Pictured are wells in Ashford-in-the-Water, Belper, Tissington and Wirksworth, photographed by Glyn Williams.
