A deep blue lake, which incidentally also inspired Eduard Mörike to write his "Stuttgart Hutzelmännlein" - written in Swabian dialect with a tongue twister: "S'leit a Klötzle Blei glei bei Blaubeura, glei bei Blaubeura leit a Klötzle Blei." of the beautiful Lau, a cross between a woman and a water nix, which her husband banished to the blue pot because she could not laugh and only bore him dead children.

The blue pot in Blaubeuren in Baden-Württemberg is the second-richest karst spring in Germany. This is where the blue springs, which after about 22 kilometers in the city of Ulm flows into the Danube.
Known is the blue pot for the depending on the light more or less intense, but always striking blue color of its water. The blue color is caused by a physical effect of light scattering (so-called Rayleigh scattering) on the nanoscale lime particles that are dispersed in the water. Due to their small size, the blue light is preferably scattered and produces the blue glow. The same effect can be observed with the Blue Lagoon in Iceland; There, the effect is caused by nanoscale silicate particles.

The blue pot is the second most water-rich karst spring in Germany after the Aachtopf.
The blue color is caused by the light scattering on the smallest lime particles in the water. Due to the small size of the particles in the nanometer range, the blue light is preferably scattered.
The blue pot is followed by a large, mostly underwater cave system, which is explored by divers. In 2006, a 170 x 50 x 50m dry cave was discovered.

What can I say - due to the incredible amount of rain recently, the Blautopf is currently more milky than blue, despite the bright sunshine today. Anyway, still impressive. You don't see it every day. In addition, it "boils" as a result, that is to say, you can see in the middle the water gushing up from the karst spring. And that's probably not seen that often, according to the locals!

Despite the many tourists, the Blautopf retains its special charm. If you stand in front of the turquoise-colored cauldron, all the myths and legends of this place come to the fore and you experience the magic that rises from the water like the Schöne Lau.

The most famous karst phenomenon in Blueburden is the Blautopf. After the Aachtopf, the Blautopf is the largest karst spring in Germany.The Blautopf owes its creation to various circumstances. The Alb plateau consists of fissured and permeable limestone. The rains on the Alb do not collect in rivers, but immediately seep into the subsoil. Extensive cave systems have arisen within the mountain range, which, depending on the water level, lead underground cave rivers or, in the meantime, are dry caves.

Clear water in an almost round lake below the slopes. With the half-timbered mill and the monastery in the background, a great sight. In the morning when there are not so many tourists and the first rays of sun just fall into the water, a fantastic sight.
