Hot Spring Colonnade
Built in a slightly less cubic spirit that the sanatorium, the Hot Spring Colonnade, or Sprudel Colonnade, is home to Vrídlo, the most spectacular spring of Karlovy Vary. Every two to three seconds a 12m-high jet of water at a temperature of 72°C shoots out from a depth of 2000m below the earth's surface.
