"Far from the mountain rock layer I come here in the light of day, I walk around many rocks, that's why I bring you calcium too."
This lettering adorns the chlorine-calcium spring near Lauenburg. It was discovered in the 19th century and was also referred to as a radium source for the first few decades. However, it does not contain radium, the name was probably only for marketing purposes, since radioactivity was considered particularly healthy at the time.
Due to its location in the forest, the spring is a popular destination for hikers. The water, which is particularly rich in calcium, is very healthy and also a welcome refreshment on the way through the Wurmbachtal.
The spring was set in stone for the first time in 1923 and renewed in 1953 as part of a voluntary work effort by the municipality. Stecklenberg owes its status as a resort to the source of calcium. It is part of the spa gardens, which have been redesigned in recent years.
