Floh und Troedlermarkt Winterthur Altstadt

📍 Steinberggasse / Neumarkt, 8400 Winterthur

On selected Saturdays from March through October, Winterthur's beautifully preserved medieval old town transforms into an open-air flea market, with around 100 stalls lining the historic Metzggasse and Steinberggasse. The cobblestone setting — narrow lanes flanked by centuries-old buildings — makes this one of Switzerland's most atmospheric smaller markets. Note: the market skips August and runs on specific dates each season; check the calendar for upcoming dates.
