A pagan protective emblem for the home, for even more powerful protection hung above the front door.
Tradition has it that the cross of Saint Bridget protects the house from fires and evil spells. The cross is associated with Bridget of Ireland (° 451 - † 525) who is venerated as one of the patron saints of Ireland.
We have the traditional 3-pointed Celtic cross and the 4-pointed cross reinvented by the church.
