The grandiose building of the Imperial Spa was built in 1878-1880 at the behest of the millionaire of Austro-Hungarian origin hailing from St. Petersburg, Anton Singer. The grandly designed Neo-Renaissance building was designed by the architect, who later also became the mayor of Františkovy Lázně, Gustav Wiedermann. Already from the beginning, the spa was equipped with the most modern spa technologies, and practically all known spa procedures were offered here. Currently the building not only serves the purposes of the balneological facilities, but also as a venue for concerts. Since 2004, a statue of Emperor Franz Joseph I stands in front of the building. The statue was created according to the original by Josef Pekárek that decorated the interior of the Main Train Station in Prague until 1919.
