The beginning of the practice of using spring water goes back to the year 1811, when Dositej Obradović visited the spring and utilized its water for medical purposes. Twenty-five years later, Russian experts and the chief of Sanitation of the Principality of Serbia, Dr. Emerih Lindemajer, carried out the first official analysis of the properties and quality of this mineral water. Impressed by the results and concurrent special medicinal properties of the water, they brought the first visitors to the source and launched the first organized exploitation of water. In 1858, Serbian prince Miloš Obrenović placed the source under the protection of the state and decided to make a city in the area. As a sign of gratitude, the locals and visitors named the spring after the prince, upon which the concept of the industrial exploitation of Bukovička Spa's naturally carbonated water began to unfold.
