Since 1998, the "twin-town flea market" has taken place every year in the car park of the Ostermann Furniture Store, the twofold aim being to raise cash for the Twinning Fund and to provide the societies linked to Witten's other twin towns with the opportunity to show what they do.
Each society can decide for itself whether to donate any proceeds to the Twinning Fund or simply boost their own finances.
A host of other clubs and institutions - schools, sports associations clubs, animal welfare groups and theatres (such as the independent Ruhrbühne) - regularly take part. An additional attraction comes in the form of commercial market stalls whose rent for the day also goes into the Twinning Fund.
Thus it is that every year there's a whole lot to do, see and enjoy. Jumble and bric à brac of all kinds, a choice of new products and an appetising range of culinary delights positively invite you to take a stroll round and have a closer look. There's also some music or sport show entertainment.
