Well dressing
The origins of the tradition are alternatively said to lie in pagan tradition or in giving thanks for the purity of the water drawn from certain wells during the period of the Black Death. It has been said to have originated in Tissington, Derbyshire in 1349.
This custom is popular all over Derbyshire.
The wells are dressed with large framed panels decorated with elaborate mosaic-like pictures made of flower petals, seeds, grasses, leaves, tree bark, berries and moss.
Wooden trays are covered with clay, mixed with water and salt. A design is drawn and its outline pricked out onto the surface of the clay.
Well-dressings are beautiful and delicate and take a lot of work to make, and yet they only last for a few days.
The well dressing season spans from May through to late September.
