So… what is a clootie well? Well, they tend to be found in Celtic areas around springs. In Scottish nomenclature, a “cloot” is a strip of cloth. They are dipped into the waters of the spring and then tied to a nearby tree while a prayer of supplication are said to the spirit of the well. (Or in modern times, saints.) Often this was done for healing, but some did it to honor the spirit of the well. Like most weird practices, there is a ton of variation.
