Every Sunday the car park near Feriköy metro turns into this massive flea market that tourists never find. Old Ottoman coins, Soviet-era cameras, vintage rugs, and random treasures spread across hundreds of stalls. Opens at 8 AM and winds down by 2 PM.

Bring cash and haggle hard. Found a 1920s Turkish coffee set for 200 TRY that would cost 2000 in any antique shop. The dealers speak broken English but they know what they have. Best finds are usually in the first hour.
