The last king of France, Louis XVI was beheaded at the Place de la Concorde. There is a story that somebody jumped on the scaffold and put his hands in the blood of the king and cried: 'Jacques de Molay, now you are avenged'. Jacques de Molay was the leader of the Knights Templar in the 14th century. He was executed near the Notre Dame, accused of heresy. Some see in this "act" after the beheading of Louis XVI a sign that the Templars "survived" for many more centuries, or even still survive as a secret organisation.
