Unter den Linden ("Under the Linden Trees") op. 30 is a waltz by Johann Strauss III first performed by the composer on June 2, 1900.
Johann III undertook a five-month Concert tour of Germany and the Netherlands in 1900. Johann III wrote to his friend on 23 March 1900:
"Now I intend to write a waltz for Berlin and call it "Unter den Linden" since curiously enough this title has not yet been used."[citation needed]
This work was premiered in Neues Königliches Opernhaus Berlin on June 2, 1900. This waltz is a representative work of Johann III. It has been occasionally programmed since, including a 2015 performance[1] and CD.[2]
