In the 15th century, the magnificent Sukiennice (Cloth Hall) that occupies the center of the Market Square was a buzzing hive of commercial activity as silk, amber, salt, leather, and spices from the East were traded within the arches of the main hall. Today the traders are Polish and in most cases speak excellent English, selling a wide range of traditional Polish handicrafts to crowds of eager shoppers. Over-sized wooden chess sets and lace tablecloths are popular souvenirs; travelers with Polish ancestry can buy traditional folk costumes for children or grandchildren back at home.
