Under the floor of Hot Spring Colonnade is located a place for drawing, distribution and thermal regulation of thermal water. There are also areas where aragonite 'grows over' the souvenirs of Karlovy Vary. Since 2008 in the old section of the thermal spring underground, the tourist route has been opened again.
The tour starts at a geological model that introduces a fundamental prerequisite for the Hot Spring Colonnade.
In the basement you can see the process, where souvenirs are made by spring water, collection of thermal tuff, clogged pipes from the beginning of the last century and a rare bacteria and algae.
