In the Low Countries, the same symbol survives as the donderbezem (thunder broom) and serves a very similar purpose. The mark is believed to protect houses from lightning, and more generally, bad luck. It is seen mostly on old farms and medieval buildings, but is still being used today as decoration. It is said to be a symbol of Donder (Donar/Þorr, etc.), whose name is the origin of the Dutch word for thunder. The shape is possibly derived from the Hagal rune.
