The Pau Casals Museum is one of the most significant testimonies of the legacy of Pau Casals, one of the most universal Catalan musicians, who revolutionised the world through innovation in playing the cello.

The building it occupies is the Vil·la Casals, which the musician had built in 1910, on the seafront in Sant Salvador, El Vendrell. Originally designed as a summer house, it was renovated in the noucentista-style, along with the Music Room, the garden and the viewpoint. Casals lived there until 1939, when he had to go into exile and never returned.

In 1972, the musician and his wife, Marta Montañez, created the Fundació Pau Casals to conserve the heritage contained in their house in Sant Salvador. After his death, La Sala del Sentiment, La Sala de Concerts and La Sala del Vigatà were opened to the public and in 1976 the house was opened as a museum.

In the current museum, opened in 2001, the visitor can admire various sculptures, paintings, musical instruments, photographs, autographs, pieces of furniture and other personal belongings of the musician, in addition to participating in various activities aimed at the promotion and dissemination of music.
