Hallenflohmarkt Markthalle Basel

📍 Steinentorberg 20, 4051 Basel

Basel's Alte Markthalle — a handsome historic hall near the city centre — becomes a flea market on the first Sunday of every month. With over 60 regular vendors offering quality secondhand goods under a stunning vaulted roof, it's a step up from a typical outdoor market in both atmosphere and curation. Rain is never an issue here.
