Europa – 70 years of Peace in Europe. The Union’s motto is “Unity in diversity”, it characterizes the way Europeans did gather, creating the European Union to act in favor of peace and prosperity, taking the most of the continent’s different cultures, traditions and languages. The dove is a peace symbol. It comes from the story of Noah’s ark. The dove carries the sign of the end of the flood that endangers the ark. The dove is carrying an olive branch and announces peace on earth.
