Radenci's mineral water (three hearts label)

Radenci’s mineral water, famously known by its “three hearts” label, is one of Slovenia’s most iconic natural treasures and a symbol of the town’s rich spa heritage. Discovered in 1833 by medical student Karl Henn, the mineral spring quickly gained a reputation for its unique bubbling sound and high-quality, carbon dioxide-rich water. By the late 19th century, Radenska mineral water was being bottled and shipped across Europe, and the town of Radenci became a sought-after destination for healing tourism.

The three hearts logo, introduced in 1936, represents the connection between Slovenia, Austria, and Hungary—reflecting Radenci’s location near these borders and its appeal to visitors from all three countries. Today, the brand is recognized for its commitment to quality and environmental care, and its mineral water is enjoyed both locally and internationally.

Visitors to Radenci can learn about the history of the spring and the development of the Radenska brand at local museums and through guided tours. The town itself, set along the picturesque Mura River, offers a tranquil setting for relaxation, spa treatments, and sampling the famous mineral water straight from the source.

While specific opening hours and admission fees for the mineral water site are not detailed here, Radenci’s mineral water remains a must-try for anyone visiting the region—a refreshing taste of Slovenia’s natural and cultural heritage, bottled with a legacy of health and hospitality.
