Charvet Clock, Turret clock in Place du Petit-Collège, Lyon, France

The Charvet Clock is a seven-meter tall turret clock with automated figures that move to mark time intervals. The structure measures roughly two meters across and stands in Place du Petit-Collège in the heart of Lyon.

The clock was created in 1864 by watchmaker Charvet and first operated in his shop window on rue de la Poulaillerie in Lyon's 2nd district. It was later moved to its current location and underwent restoration to bring its mechanisms back to working order.

The clock is nicknamed "horloge aux Guignols" after Guignol, the Lyon silk-weaver puppet, and his companion Gnafron, who strike the largest of five gilded bronze bells. Harlequin and Polichinelle from the commedia dell'arte sound the other bells every quarter hour. The soldier Trompette, added after the 1870 war, blows his bugle for the hourly chime, and his costume has changed with political events.

The clock is set into the facade of the Hôtel de Gadagne at 1 place du Petit-Collège, in Lyon's 5th arrondissement, above the entrance to the museums of Lyon history and puppetry. It faces the public street, so it can be seen without entering the building; the mechanism and figures are viewed through glass.

The soldier Trompette, added after the 1870 war, sounds the hour on the largest bell, while Guignol and Gnafron strike it and Harlequin and Polichinelle ring the other bells every quarter hour. His costume was changed as political events unfolded. The five bells are gilded bronze.
