Celtic-cross is generally used symbol of Christianity but the history of this symbol can be dated back beyond the existence of Christianity. The four arms in the cross signify the four elements namely earth, water, air and fire; the four directions east west north south and the essential four parts of a human body. Mind, heart and soul.
In Germany, the Celtic cross was adopted by a neo-Nazi party, so the government banned its public display.
