Karlovy Vary prides itself in its colonnades. They were built in the 19th century and beginning of the 20th century and there are five of them – the Mill Colonnade (Mlýnská kolonáda), Park Colonnade (Sadová kolonáda), Market Colonnade (Tržní kolonáda), Chateau Colonnade (Zámecká kolonáda) and Hot Spring Colonnade (Vřídelní kolonáda).
Probably the most beautiful is the Mill Colonnade in the Neo-Renaissance style. It is 132 meters long, 13 meters wide and has 124 columns. It stretches over five hot springs.
The Hot Spring Colonnade is where you can not only drink the curative waters of the Vřídlo (literally “Hot Spring”, temperature 73°C/163°F), the best-known of the springs and symbol of Karlovy Vary, but also admire the 14-meter high fountain that constantly springs up from the Vřídlo in the covered hallway of the colonnade.
