Flea Market Barcelona is an exchange of reasonably-priced second-hand items in good condition. It does not include crafts or anything manufactured.
This month's flea market will take place in Plaça Blanquerna del Raval on Sunday February 19th from 11am-6pm. Come and revel in the emptied wardrobes and drawers of Barcelona's residents.
Or, if you're interested in taking part in the flea market yourself, send an email to firstname.lastname@example.org expressing your interest and what you wish to sell. There is a fee of 20€.
