The first source was discovered by a farmer who was looking for sulfur to sprinkle his vines. After the end of the Second World War, the residents blew the rocks with dynamite and spilled the hydrosulphur water at a temperature of 39 o C from the volcano, where the new Thermopigi was created. Originally it was named the source of Saint Nicholas and later Agia Paraskevi. At the site of the springs, in the first years a small parapet with two halls was created and in 2000 the new ultra-modern building was built. Thus, a small spa was developed, the source was dedicated to the grace of the Zoodochos spring and reconstructed its chapel.
