Lake Heviz, Heviz

Lake Heviz is one of the wonders of Hungary and the largest thermal lake in Europe. More than a million tourists come to the healing waters every year! This is the most visited place of Hungary after Budapest. And that’s not surprising: warm thermal waters heal from many ailments, help to maintain and strengthen health. A small town with excellent infrastructure is built right at the lake. Moreover, this is the land of pink lilies and bright colors!

Lake Heviz: history and origin

  • Origin. Heviz is an ancient lake which appeared thanks to the basaltic mountains towering near Balaton. According to philologists “Heviz” means “flowing thermal water”.
  • Legends. The miraculous power of lake waters has been used for more than 2 thousand years! Even the Romans noticed that the thermal lake helps to heal. The legend has it, the source that feeds Lake Heviz started to well out during the days of Roman civilization. The nanny of the paralyzed child prayed the Most Holy Virgin to cure his illness. Prayers were heard: a miraculous source appeared which saved the child from the illness. This child was the future emperor of Eastern Rome, Flavius Theodosius. However, according to research, this lake’s history begins with the ancient Pannonian Sea.
  • First thermal baths. For the first time, a research study of water was conducted in the mid-18th century. It was decided to create thermal baths on the miraculous lake. Count György Festetics who put a lot of effort into developing the resort was involved in the construction. Heviz, however, became widely known only in the early 20th century when the owner of the brewery rented it. He approached this with typical for him entrepreneurial mindset. Famous doctors were invited to develop new methods of treatment and prevention. Rumors of miraculous healings spread throughout the country. In the early 20th century, Heviz became the most famous thermal spa of Hungary. And it remained that way until the beginning of the Second World War. When it ended, the baths were nationalized. A specialized clinic for the treatment of rheumatological diseases was built on the shore of the lake. Baths were reconstructed in 2005: a modern health center was created on the lake as well. Every year more than a million tourists come here. Among them, about half are Hungarians, a third are Germans, and another third are Ukrainians and Russians.
  • Lake Cave. The lake water completely replenishes itself every three days. For a long time, the source of Lake Heviz remained in secret. In the mid-19th century, the baths were once again rebuilt, and measurements were taken. When the measuring instrument was submerged to find out the depth, the rope holding it broke from overstrain. That’s how the source which is 38 of water depth was discovered. The lake is funnel-shaped. For quite a while, it was impossible to work at such a depth: just too dangerous. Only in the 1970s divers finally saw the source. The power of the lake lies in the 16-meter cave which is located at a depth of 41 meters. Thermal springs of different temperatures mix together and reach a temperature of +38 C. Then they flow along the “corridor” to the top feeding Lake Heviz. Therefore, the water in Heviz is always fresh and flowing!
  • Water lilies. Swimming in the turquoise waters of the thermal lake covered with water lilies – this is possible only in Heviz. White, pink and purple lilies have become constant residents of the amazing lake and that’s because in 1898 one professor brought lilies and water lilies to the city. Amazing flowers took root and became a symbol of Heviz!
