In 1325, Wielopole already had a parish church of St. Mary. The town remained in private hands; after the Bishopric of Lebus, its owners were the Kamieniecki family, the Frysztacki family (1492 - 1518), and the Maciejowski family. In the late 15th century, 111 families resided in Wielopole, with a few artisans. In the first half of the 16th century, town’s owner Kacper Maciejowski began to invest in Wielopole, building a Renaissance castle. The town however did not emerge as an important trade center. It belonged to Sandomierz Voivodeship, and its situation deteriorated after the Swedish invasion of Poland, when both Swedish and Transilvanian armies of George II Rakoczi burned and ransacked it. In the 18th century, Wielopole declined further, and following the Partitions of Poland, it found itself in Austrian Galicia.
