Architect Zítek’s original vision of the appearance of this new renaissance building differed from its final look substantially. The renowned architect initially designed the building as a two-storey, much more ostentatious structure. Once finished, the colonnade was not received with the warmest feelings and appreciation. Purportedly, it was not in tune with the nature of the spa city. Since 1893, when it was extended to the Rock Spring (Skalní pramen), it has been 132 m long. Its roof supported by 124 Corinth-style columns shelter an orchestra pit and five mineral springs. Its premises are decorated with allegoric statues.
