The same year, the known chemists, M.T. Leko made the first analysis of the water and determined that it was really thermo-mineral water in question, with significant healing capability (later on confirmed by repeated tests), since

„according to the quantity of sodium-bicarbonate, it is stronger than that of Selters spring, but contains somewhat more salts and… according to its content of lime and magnesium, it is a cleaner alkaline water than the Selters water“.

And so, there arose a Spa on the brim of the small town of Mladenovac of the time (established in 1882) – which, often compared to the famous health resort in Essen (Germany), was named – Selters. (The water received international recognition in 1903.)

Selters Spa - Mladenovac Serbia

Selters Spa of Mladenovac is situated on the slopes of the Mount of Kosmaj (630 m), on a spacious wooded area – in midway of the Belgrade-Kragujevac road (50 km south of Belgrade.)

Owing to the favourable location, (136 m altitude), and dominant winds from the Mounts of Bukulja, Vencac and Kosmaj, the air in the Spa is clean and the climate is refreshing (moderate-continental, with lots of sunny days in the year.)

The healful waters issue from two springs.
The older one provides alkaline-muriatic acidic water (31°-32° C), rich with sodium hydro carbonate and chlorine.
The other spring, in use since 1978, issues the water that belongs to the group of alkaline muriatic carbon-acidic hyper-thermae (50° C). Thanks to its physical and chemical features, the water belongs to the category of mineral waters of a wide spectrum of medicinal properties, and is used as a significant therapeutic means by bathing, inhalation and drinking.
