The white wooden colonnade designed by architects Fellner and Helmer was originally a temporary structure. However, it has lasted for over 130 years and time has not detracted from the beauty of the richly carved Swiss-style building with its columned arcade and gabled roof. An interesting feature is the relief of Charles IV depicting the legend of the founding of the city.

SPRING OF CHARLES IV.
The healing powers of this spring may have contributed to Emperor Charles IV's decision to build a spa here. The discovery of Karlovy Vary is evidenced by the relief above the spring. The spring has been lost and rediscovered several times since its discovery (1838). Several boreholes have been drilled, thanks to which it can still be prescribed by spa doctors today.

CASTLE LOWER SPRING
It springs inside the former Castle Colonnade (today's Castle Spa), built according to the plans of the Viennese architect Ohmann. Behind the spring vase is a sandstone relief depicting the "Spirit of the Springs".
