The legend of the Rogaška springs originates in the 17th century. Apollo, the healing and sun god, stopped the winged horse Pegasus as he was about to fly to Mount Parnassus: "Don't fly to the sinful Parnassus! There is nothing but lies and vanity there. Here is the source of health and true divine power. Instead of Hippocrene, drink Roitschocrene, the Rogaška spring in front of you!"

Rogaška Slatina has a centuries-long tradition, placing it among the oldest and most important health resorts in Slovenia and Europe. Archaeological remains and the Roman road which connected Celeia and Petovium provide evidence that even the Celts and the Romans were familiar with the Rogaška Slatina area.

In 1665, Peter Zrinski, one of Europe's mightiest rulers of his time, recovered after drinking mineral water from Rogaška Slatina, an event which quickly spread the fame of this healing water. This was the birth of health tourism in Rogaška Slatina.

In 1803, the small village started to develop into a modern health center. First hotels were built in the 19th and at the beginning of the 20th century: Hotel Zdraviliški Dom (today's Grand Hotel Rogaška Superior), Hotel Styria, Hotel Strossmayer, and the main Spa Hall (today's Crystal Hall). All the hotels were renovated in 2003 to provide every modern comfort while retaining the impression that time in Rogaška Slatina has stopped. The famous guests to have visited our health center include the royal families of Habsburg, Bonaparte, Hohenzollern, and Karadžordžević. The rich social life culminated in 1846 with the concert of the famous pianist Franz Liszt.
