Kamnica, first mentioned in historical sources even about 1100, is situated on a territory which was strongly colonized at the beginning of the late Middle Ages; especially viniculture should be mentioned which was very attractive for Alpine monasteries and the inhabitants of the neighbouring Maribor. The Benedictine monastery of St. Paul in Lavanttai had extended possessions here since its foundation. The church had become a vicarage latest in the XIII. century and was mentioned already about 1100. In 1506 the parish of Kamnica along with that of Maribor, of Selnica and St. Peter was incorporated to the diocese of Gurk which caused numeral collisions dealing with the nomination of vicars and inspections between the bishop of Gurk and the archbishop of Salzburg who was the local ordinary. In the second half of the eighteenth century in the branch establishment of Kamnica two independent spots were formed at Sv. Križ (Gaj) and at Zgornja Sv. Kungota whereas the church at S. Urban remained a branch establishment of Kamnica up to now. During the Josephinian reorganization of the episcopal (diocesan) borders the parish of Kamnica was incorporated into the diocese of Seckau but after the shifting of the Levantine episcopate from S. Andra In the Lavanttal to Maribor in 1859 it belonged to the diocese of Lavant respectively of Maribor.
