Thor, the Norse god of Thunder, was the most powerful Norse god. Thor's Hammer, called Mjolnir (lightening) is perhaps one of the best known and historically most important of all Norse mythology symbols. The Thor's Hammer symbolizes protection, power, strength, growth and good fortune. Thor's Hammers were often used to bless or protect during weddings or births.
