During the Middle Ages, export was administered mostly by German merchants living by the squares Kornhamnstorg ("Grain Harbour Square") and Järntorget ("Iron Square") on the southern corner of the city. Regional peasantry supplied the city with food and raw materials, while the craftsmen in the city produced handicrafts, most of whom lived by the central square Stortorget or by the oldest two streets in Stockholm, the names of which still reflects their trade: Köpmangatan ("Merchant Street") and Skomakargatan ("Shoemaker Street") in the central part of the city. Other groups lived by the eastern or western thoroughfares, Västerlånggatan and Österlånggatan.
