The health and spa resort Rogaška Slatina is, with its centuries-long tradition, one of the oldest and most important resorts of such kind in Slovenia and in Europe. Excavations and an ancient Roman road, passing through Lemberg and Rogatec on its way from Celeia (today's Celje) to Petovium (Ptuj), prove that the area around Rogaška Slatina was already known to Celts and Romans. In the immediate vicinity of the Tempel spring a Roman bronze needle with six heads was found, and Celtic coins were found in a well in the nearby village of Kostrivnica.
Wherever they arrived, Romans used local natural resources, especially hot water springs. At the time, Rogaška Slatina did not have hot springs, but it had excellent mineral water. We can say with a great degree of certainty that Celts and Romans knew about that mineral water and drank it, since it was their habit to throw coins or other valuable objects into water springs as they believed that it would win them the favor of gods who resided in those waters.
In 1803 a small village surrounding the springs started developing into a modern health and spa resort. It was founded by Styrian States headed by the governor, Count Ferdinand Attems, and already in 1804 it had its first resident doctor. First major accommodation and health buildings were built at the time, including the main hall and the oval pavilion Tempel that still exists today, rising like a crown above the former main spring.
The number of visitors to Rogaška Slatina increased year by year, so that only some thirty years after the first construction work much larger accommodation facilities had to be built. Newly built hotels emphasized the chic character of the resort, and between 1840 and 1860 the image of the resort was created, which has remained essentially the same until today. In the early 20th century old classicist hotel buildings were joined by many new ones, built in the Art Nouveau style. Between the two world wars Rogaška Slatina was the most important and most modern health and tourist resort in Yugoslavia.
Thanks to its unique natural mineral water Donat Mg, with a high mineral content and the highest magnesium content, after the Second World War Rogaška Slatina developed into one of the most beautiful health and spa tourist resorts in Europe, where mineral springs were later joined by a thermal spring and the construction of a swimming pool complex. Today Rogaška Slatina is one of the best known and most highly qualified health resorts for the prevention, further therapy and rehabilitation of the illnesses of the digestive tract and metabolic diseases (diabetes, high cholesterol level, excess body weight), managerial and psychosomatic diseases.
