District capital city, located approx. 50 km to the north-east of Poznań, on the road to Toruń.

When Poland was ruled by Boleslaw I the Brave, the king was once visited by Bishop Wojciech. He was a righteous and pious man who decided to dedicate his life to the conversion of the pagans. So he took a mission to the pagan tribe of the Prussians who were famous for the art of war and cruelty. They also treated the strangers who tried to impose their teaching upon them in a cruel way. Bishop Wojciech was murdered, his body was quartered, and his companions were expelled.

When the sad news reached Boleslaw the Brave, he decided to pay for having the body of the martyr returned. The Prussians, however, gave a very steep price. The king was to give as much silver as the martyr's body weighed. Thus the Polish king sent messengers with the desired amount of the precious metal. The Prussians were waiting with a scales. The body of the Bishop was put on one scale pan, and the other pan was waiting for the silver. So the king's messengers started to put silver coins and utensils, piece by piece, on the scales, but it did not budge.

The bags were already empty and it seemed that they would have to return to the king's court with nothing. Suddenly, a poor widow appeared in the square. She noticed the trouble the messengers were in and decided to throw in her gift. When the widow's mite was thrown on the scales, it finally budged. To ensure accurate measurement, they started to take silver objects off the scales. The balance was finally achieved when the widow's mite was the only thing that remained on the scales pan. The Prussians were amazed at this miracle and so they understood that they had killed a holy man. The messengers took the body and put it in the tomb first in Trzemeszno and then in Gniezno, where it has been resting until today.
