Every year a small flock of sheep is herded across the Fouer to mark the start of the funfair.
According to historian Steve Kayser this tradition dates back all the way to 1402 when there was a shooting stand at the Fouer at which the best shot could win a sheep.
The winner then paraded the sheep through town to the sounds of the “Hämmelsmarsch”, the mutton march.
Every year, it is said that around two million visitors make their way to the Fouer.
