Horseshoe

Drawing on the strength and power of a horse, horseshoes are powerful good luck charms. A legend of Saint Dunstan from the 10th century says he trapped the devil in a horseshoe; thus, putting one above your door protects your home from evil. An upward facing horseshoe is said to gather luck and a downward facing one is said to cover you in good luck. (Though, we re not entirely sure what s the difference between those two.)
