The biggest and most remarkable Colonnade of Carlsbad (Karlovy Vary) was planned in her original form as a 2-storied building, nevertheless, the construction had to be reduced because of the huge costs.
The Mill Colonnade covers six springs:
The Water Nymph's Springs (Rusalka 60°C)
The Rock Spring (Skalní 53°C)
The Mill Spring (Mlýnský 56°C)
The Libuše's Spring (Libuše 62°C)
and the two Springs of the Count Wenceslas:
Kníže Václav I 65°C
and Kníže Václav II 58°C
