Visitors can find the Waldstein Monument behind the headquarters of the Mariánské Lázně spa company. It was built in 1836 in honor of an illustrious visitor Earl Ernest von Waldstein-Wartenberg.
In Felbinger's chronicles of Mariánské Lázně, the monument is depicted as a grey marble vase standing on a pedestal with a poem celebrating the Earl's benefaction to the poor. The Earl died in Mariánské Lázně in 1832. A replica of the vase was created by V. Eibl during the 1960s, but was destroyed several days after its installation.
