The name likely comes from "bule" or "bure", which designates a large square or conical pile of branches, high enough to be burned. The name of Bules is seen in a Latin form, in a charter for the city of Orval in 1174. Later, in 1230 and 1271, Bures is also mentioned. Bures comes from the Latin meaning Burer burn. A bonfire celebration was also lit the annual day of bures, also called "day of the brandons."
