The headless statue of St Denis whose statue can be found all over Paris including on the Notre-Dame and the Eglise St-Germain-l’Auxerrois. Saint Denis was the first bishop of Paris who met his death around 273 A.D. According to legend, Roman soldiers tortured Denis near the present site of Notre-Dame and then decapitated him on the slopes of Montmartre. There the martyred saint picked up his head and walked northwards almost 4 miles to the place marked by the cathedral that bares his name.
An interesting story, though quite imaginative as the legend was created several hundred years after the – no doubt real – event. Wherever you see him depicted, he is the saint who patiently holds his head in his hands.
