From 10 a.m. to 9 p.m., the great puppeteer of Ducal Square presents the legend of the Ardennes - the four sons of Aemon - in a series of 12 panels. With each passing hour, the motor plays three beats and opening music and then announces the time, telling visitors the story as it plays the puppets animation, then the show ends with closing music and the curtain closes, and after a few minutes of the show, everything automatically realigns to run again over the next hour.
