Vřídelní kolonáda, Functionalist thermal spring colonnade in Karlovy Vary, Czech Republic.
Vřídelní Kolonáda is a spa building from the 1970s with a concrete structure and glass elements that houses the town's most famous thermal water. At its center, a geyser shoots thermal water up to 12 meters high through a dome.
This building was completed in 1975 and replaced older structures that had housed the spring since 1826. The functionalist style reflects how the spa transformed during the modern era.
The spring room with its five fountains sits at the heart of Karlovy Vary's spa culture. Visitors drink the water directly at marked points following traditional bathing customs and experience the daily rhythm of spa life.
The underground section with guided tours from May to September shows how minerals form and sediments build up. Access to the spring itself is straightforward, but expect more visitors during the warm season.
The spring produces roughly 2000 liters of water per minute and is the hottest and most abundant in the town. This exceptional water abundance is what first made Karlovy Vary famous as a spa destination.
