This historic square was a Jewish market in the pre-war days, with its rotunda serving as a kosher slaughterhouse. Today you'll still find butcher shops inside, while fast food windows line the exterior. In the open trading stalls surrounding the roundhouse produce and junk are sold daily. It's a different, often unpredictable scene on the square each morning, but Saturdays are generally reserved for more junk/antiques and Sundays for clothing, while Tuesday and Friday mornings it's a full-on rabbit swap and pigeon fair - one of the most bizarre spectacles you can possibly witness if you arrive early enough (ends about 9:00). Markets begin around  5:30 in the morning and generally end by early to mid-afternoon depending. In the evenings, Plac Nowy turns into one of the best drinking destinations in town, lined with atmospheric bars.
