A fascinating peek into spa culture is housed in this small museum, just off Národní ulice. There's a wonderful collection of spa-related antiques, including copper bathtubs and a turn-of-the-20th-century exercise bike called a Velotrab. The guest books provide insight into the cosmopolitan world of pre–World War I Central Europe. The book for 1812 contains the entry "Ludwig van Beethoven, composer from Vienna." There are also rotating exhibitions of graphic arts.
