Delle Flea Market — Les Cartes Delloises

In late June 2025, Delle's stadium hosted the annual flea market organised by the association Les Cartes Delloises. Between 50 and 100 private sellers occupied the stadium grounds from 6am to 5pm, offering a variety of second-hand items at affordable prices. Delle residents and visitors from the Belfort Sundgau, including some regulars from nearby Switzerland, enjoyed this day of bargain hunting in the border town.
