This beneficial spring is located in the municipality of Dežanovac. The proclamation of the spring in the forest valley northwest of Kreštelovac was encouraged by priests, and thus the source of healing water, Svetinja, became a shrine in 1747, which is still visited by people of all denominations. At the site of the healing natural water source, a modest Orthodox wooden chapel was first erected, and later a brick chapel of the Assumption of the Holy Virgin was built. The permanent source of cold drinking water that sprang up near the chapel was given a halo of sanctity among the people.
According to widespread belief, the water from the spring in this forest has the power to miraculously cure diseases, and according to the claims of the local people, there were many cases of healing of the sick, even the disabled, after they bathed in the water from the spring in Svetinja. Through the mediation of the Catholic clergy, in 1773, the water from Svetinja in Kreštelovac reached Vienna for analysis. The results of the analysis of the water from Svetinja were included in the list of well-known sources of medicinal water in Croatia and Slavonia, compiled by the physician J. B. Lalangue, a doctor from Varaždin. Kreštelovac and the source of medicinal water were mentioned in 1782 in the travelogue from Požega County created by professors from Pest, M. Piller and Lj. Mitterpacher. The charisma of the holy water has been preserved to this day.
