The Zámecké lázně (Castle Spa) is located in the heart of the Carlsbad spa zone, in the vicinity of the Market and the Hot Spring Colonnade. Zámecké lázně (the Castle Bath) is one of the most beautiful spa centres in Europe and to its guests, it provides a wide range of curative and relaxation programmes. In 1909, architect B. Ohmann was successful in an large-scale competition and the Castle Colonnade was built in the course of years 1911 - 1913 according to his project. It was preserved unchanged until the beginning of a radical reconstruction and conversion into the Castle Spa in 2000. In this case as well, B. Ohmann proved his mastery in applying a ingenious combination of various architectonic styles, when leaving a charming roundel in the upper part of the structure inspired by antique architecture. As a symbol of balneology, this roundel remains as one of the beautiful and characteristic features of traditional craftsman ship in Karlovy Vary to the present day. While preserving all the essential architectonic elements, a radical reconstruction of all the premises of the Castle Colonnade was executed in 2000 and 2001, generously converting the structure into a comprehensive curative facility called the Castle Spa. The fundamental credo of the Castle Spa is returning to traditional Carlsbad spa treatment. Providing comfort, atmosphere, and individual care – all that the visitors of the spa in Karlovy Vary had been used to in the era of the “Golden Age”. Everyone can find this (as well as something extra) in a more than abundant extent in Karlovy Vary, especially owing to the Castle Spa.
