During the 12th and 13th centuries, in the high to late Middle Ages, a complex of settlements was centred on the location of today's "Stare Miasto", where there existed a large settlement named Konin and a market place and a church built of sandstone. (The name "Stare Miasto" first appeared in use later, after Konin had been reestablished elsewhere.) What remains from that time is SS Peter and Paul's Parish Church, with its magnificent carved portal and a solar clock on the south wall, perhaps the oldest solar clock in Greater Poland. In 1331, the settlement was plundered and burnt by the Teutonic Knights. What remained was soon abandoned and the town of Konin was reestablished, six kilometres () to the northeast, in the more defensible spot where the Old Town of Konin is situated today.
