The West Bohemian town of Carlsbad (Karlovy Vary) was a popular spa resort among the members of the modern European elites due to its therapeutic baths. Carlsbad gained a reputation as an important balneological center not least due to the stay of prominent personalities such as the Russian Tsar Peter the Great (1672–1725). In the course of the building boom in the second half of the 19th century, which was dominated by Art Nouveau, the city finally acquired its present appearance.
