The ruins of the church are located in the former village of Chojnice and now a military training ground in Biedrusko. Once a lively village, a parish of several nearby villages such as Biedrusko or Suchy Las, today the ruins of the church are in the center of the military training ground without any trace of any other buildings and a few cemeteries forgotten in the forest.
The exact date is not known of the erection of the parish in Chojnica. Church documents show that this took place at the turn of the 11th-12th centuries.
At the beginning, Chojnica was the center of several smaller estates related by neighborhood, the so-called opole center (opole - an opolna organization, in the twelfth-thirteenth century settlement unit of western Slavs) and had its parish church p.w. St. John the Baptist (X-XI century) - this church is mentioned in the sources before 1374 and it may have existed already in the 11th century.
