According to the plan, the white wooden building, built in the Swiss style, was supposed to cover the springs for only a few years. However, when it had stood over the springs of Tržní and Charles IV for more than a hundred years, the city proceeded to preserve it and completely reconstruct it. Like a number of other buildings in Karlovy Vary, the Market Colonnade also comes from the workshop of Viennese architects Fellner and Helmer.
The colonnade is covered by a saddle roof and is closed on 3 sides by wooden walls. The front wall consists of a columned arcade. The market colonnade is decorated with various lace motifs carved into wood. Also interesting is the relief depicting the legend of the discovery of Karlovy Vary above the spring vase of Charles IV’s spring.
