Genevans also traditionally celebrate the failure of a Savoyard attempt to invade the city in 1602. The celebration, which takes place in December, is called L'Escalade, and includes a parade in the Old Town, a marathon, and numerous costume parties across the city. Inhabitants generally eat vegetable stew to commemorate a fictional character called Mère Royaume who is said to have thrown boiling hot soup on the Duke of Savoy's men when they were climbing the walls of the city during the night (hence the name L'Escalade, which means "the climb" in French). Traditionally, children are encouraged to knock on people's doors and sing songs in old Genevan, while teenagers generally throw eggs and flour at each other. Another tradition is to cross a pot made of chocolate filled with marzepan vegetables while saying "and so perished the enemies of the Republic".
