Underneath the Spire Flea Market

Those intending to hunt for antiques or looking for a proper flea market experience - dust mites, mothballs, and all - will do best to try their luck at the Centennial Hall, where vendors set up shop monthly underneath the Iglica spire. While not huge, the market is a reliable source of dusty porcelain, tarnished jewellery, and vintage mechanical contraptions. If you get the timing right and have a bit of change on you, you can continue browsing inside the Centennial Hall, which charges a few złoty for entrance to its various themed fairs - though depending on your luck you might end up at a stonemasonry expo or something equally exciting.
