The first written note mentioning Piešťany was found in the charter of the King Koloman I., dated in 1113. The settlement was the property of the Bana Castle destructed in the second half of the 13th century. Since the 16th century it was already mentioned as a small town (oppidum). The name Piešťany is derived from the word “piesčina”, which means a sand bank, because the soil basis is due to the river sediments sandish.
Man utilized the thermal springs since ancient times. The water here does not freeze, even in the coldest winter. The exact time when the balneological treatment in hot springs was started is difficult to determine certainly. It can be assumed that it originated and began developing on the basis of folk medicine, as early as in the second half of the 15th century. The patients and visitors were bathing in primitive holes dug around the springs, filled with thermal water. Over them shelters were erected, made of boughs and twigs, protecting them from rain. As dwellings they used the simple peasant houses.
First more detailed description of Piešťany as the spa town was found in the document written by Juraj Wernher, brought out in Basel and entitled „De admirandis Hungariae aquis hypomnemation” – About The Miraculous Waters Of Hungary. He described in this book the different spa towns in the Hungarian monarchy, Piešťany as the most healing in the whole monarchy and he brought its fame.
By a propagation of the good reputation and a development of the spa, in the second half of the 16th century were multiple medical books about Piešťany brought out, among them one from Italien Andreas Bacciuso, the personal physician of then pope Sixtus V.
