The most inconspicuous colonnade. If you climb the stairs located between the Market Colonnade and the Plague Column (pictured below), you will get directly to it. It was built in 1910-1912 by the Viennese architect Johann Friedrich Ohmann. Only the source located in the round pavilion (in the picture below) is available to everyone. The rest of the colonnade is accessible only to those living in the Castle Resort. This is probably why many people, even those who have visited Karlovy Vary many times, cannot confidently show the location of this colonnade. I've told you the way to find her unmistakably.
One of the 5 colonnades of Karlovy Vary.
It consists of two parts: the colonnade of the Upper source and the colonnade of the Lower source.
The first of them is publicly available, and the second is only for clients of the Castle Hospital.
