Originally called the New Spring, it received Empress Caroline Augusta's name in 1819. It is traditionally prescribed for kidney stones of unknown composition and for oxalate stones; whether it belongs in your treatment plan is decided by the spa physician. According to Ensana's 2025 medical catalogue, its composition has changed in recent years and its magnesium and calcium content has fallen. It lends its name to the Caroline Spring colonnade, one of the town's most photographed structures.
A little history
The spring was discovered in 1809 during work on the promenade between the Cross Spring and the Central Baths and was at first simply called the New Spring. In 1811 a gazebo on eight Corinthian columns was built over it, replaced in 1872 by a raised two-winged colonnade. For a long time the spring served only for baths at Nové Lázně; it was brought back to the colonnade in 1981. In 1986–1990 the colonnade was replaced by a replica set 12.8 m closer to the Cross Spring; the original outlet is marked in the stone paving.

How the drinking cure works
The water is sipped slowly, usually before meals — traditionally from a spouted spa cup that guides it past the front teeth. Which spring, how much and how often is set by your spa physician, because every water acts differently. This page informs; it is no substitute for medical advice.
