The historic building dating back to the 16th and 19th centuries. The seat of the Gaszyn family located near the parish church. Only ruins have remained until the present day. The first written mention of Kietrz, called Ketre (Katscher) at that time, was made in 1321, when the Olomouc Bishop Konrad I granted the municipal charter to Kietrz. More precisely, the bishop mentioned Kietrz as a town in his document "Law on the change of fields". Year 1321 is assumed to be the date when the municipal charter was granted. As a small town, Kietrz did not have defence walls but, according to the records from 1451, it was fortified with embankments and moats. From that time also a medieval urban layout of Kietrz has been preserved. Kietrz was in the hands of the Olomouc Bishops until the 17th century, when it was passed over to the Gaszyn family.
