If you're a jazz lover, this is a great series of concerts taking place every Saturday in the picturesque surroundings of Warsaw's Old Town. Drawing over 40,000 festival-goers annually and into its 27th year now, this open-air festival promises to be the largest and most popular jazz festival in Poland. Check out their website for the full schedule of who's playing when and don't forget, it's all free. If you ask us, that's a pretty reasonable price to see some big names in the Polish jazz scene.
