Spring František is the oldest known mineral water spring in Františkovy Lázně. It was already known in the Middle Ages, when "carriers" of water brought it as table water to nearby Cheb. According to the nearby village of Slatina, the spring was also called Slatinná kyselka or Chebská kyselka. Around 1600 it had a reputation as one of the most healing springs in Europe and was exported in ceramic bottles to all major cities.
In 1789, the Spring František was covered for the first time with a wooden pavilion with a grille and the water was drained into a reservoir for hygienic reasons. The water carriers, who perceived this act as an interference with their inherent rights, subsequently demolished the pavilion. The whole action then gave rise to the foundation of Františkovy Lázně. A second wooden pavilion was built in 1793 at the time of the spa´s foundation and stood over the spring until 1832. Then the present brick pavilion with Doric columns was built, which has been preserved in its original form and is still one of the symbols of Františkovy Lázně.
