Even though the historic data on the castle and its owners are very scarce, according to the testimonies of people, who worked for the counts, experts managed to reconstruct a part of the story. It is, therefore, known today that the manorial estate in Suhopolje at the end of the 18th century was purchased from the Imperial Chamber by Count Ivan Nepomuk Janković. The exact year is not known. Ivan Janković purchased an already fully formed estate with a series of housing, governance and farm buildings the construction of which was completed in 1775. The estate was mostly of economic importance and the Count himself allegedly did not spent much time there. However, he had an impressive classicist church built that then formed the town of Suhopolje. In 1816, it was consecrated to St. Therese and, a year later, Ivan Janković was buried there and several years thereafter his wife Therese, born Püchler, was buried there, too. Ivan was inherited by his son Stjepan and in the second half of the 19th century the new heir was Count Elemir. He proposed to a Hungarian noble woman but, having seen the space in which they lived, she rejected him. She said that this was only a field. In order to please his wife-to-be, the young count, had other buildings built within the castle estate beside the already existing building. The park was planted at that time as well with mature tree seedlings in order to be as lush as possible.
According to oral tradition, the family also had a menagerie, i.e. hunting grounds on Odboj in Bjeljevina. There Count Elemir asked his father Aladar to permit him to get married to Ilka, the administrator’s daughter. Aladar gave his permission only after he had him whipped in front of everybody.
