Rauracherstrasse 33, 4125 Riehen

The Quartierflohmarkt Riehen/Niederholz turns the entire Niederholz neighbourhood in Riehen into a sprawling open-air flea market for one Sunday a year. Private residents set up stalls in their gardens, courtyards, and driveways across the district — locations marked with balloons for visitors to follow. Pick up a map, follow the balloons, and see a side of Riehen most visitors never get to discover. One of 17 neighbourhood flea markets organised across Basel and Riehen by Verein Stadtprojekt throughout the season.
