Rogaška Slatina is Slovenia’s oldest and largest spa town, a veritable ‘cure factory’ with most visitors here to undergo the various medical treatments and therapies offered by the renowned Rogaška Medical Center. Its location, set among scattered forests in the foothills of the Macelj range, does attract some, mostly older, recreational visitors, who come for the area's hiking and cycling opportunities.

The hot spring here was known in Roman times but first made it onto the map in 1572, when the governor of Styria took the waters on the advice of his physician. A century later visitors started arriving in droves and by the early 19th century, Rogaška Slatina was an established spa town.

The heart of Rogaška Slatina is the spa complex, an architecturally important group of neoclassical, Secessionist and Plečnik-style buildings surrounding a long landscaped garden called Zdraviliški trg, or Health Resort Sq.
