The thermal water (temperature: 30°C/86°F) is reputed to reduce joint pain, and since it has a lower salt content than most thermal waters (around 1000 mg/liter), people can bathe in it for much longer, practically an unlimited amount of time. The Cave Bath can be visited all year long, except for January.
The cave and the thermal spring have been known since ancient times, but Tapolca became a popular bathing place only after the Ottoman occupation of Hungary (16th-17th century). During this time the area belonged to the Greek Orthodox abbey of Görömböly; the development of Tapolca into a bathing place was the idea of the abbot in 1711. He also brought doctors from Kassa, today Košice, Slovakia to examine the beneficial effects of the water. Three pools and an inn were constructed in 1723. The cave itself was not used yet, as the pools were outside. The water was colder than it is now, because the cold water springs of Tapolca (which now play an important role in providing Miskolc with drinking water) were used too. By the mid-18th century, after a short period of popularity, the bath was neglected and by the 19th century the buildings were in ruins.
