Karlovy lázně (; meaning "Charles' Spa") is a nightclub in Prague, Czech Republic, situated 50 meters from the eastern end of the Charles Bridge on the bank of the Vltava River. The building housing the club was a bath-house dating from the 14th century, and retains some original features, such as mosaic wall tiling and Roman spa-pools now used as dance floors. The club has five floors, with each floor playing a different style of music, a fact which features heavily in the club's marketing. Karlovy Lázně is the largest club in Prague, and claims to be the largest nightclub complex in Central Europe.
