The house in which Wolfgang Amadeus Mozart was born on January 27, 1756 is one of the most visited museums in the world. The Mozart family has lived here for 26 years. The owner of the building was a family friend Johann Lorenz Hagenauer. The first museum dedicated to the life and work of the Great Composer was opened on June 15, 1880 in this building by the Mozart International Foundation. Over the centuries, the museum was systematically reconstructed and expanded, which allowed it to become a cultural center, attracting annually thousands of visitors from all over the world to Salzburg. The museum is located on three floors of the building. Permanent and temporary exhibitions tell visitors about Mozart: how he grew up when he started to write music, who were his friends and patrons, and what kind of relationship Wolfgang had with his family. In the halls of the museum you can see authentic documents, memorabilia, portraits of the family and the composer himself, painted during his lifetime. The first floor of the museum offers visitors a plunge into the daily life of the Mozart family. Travel accessories from the 18th century, household items, original documents and paintings tell about the events that took place in the Mozart family in Salzburg and away from home. One room is furnished with original furniture on the model of the living atmosphere of that era. The Mozart International Foundation has created a special exhibition, “Child Prodigy Day”, dedicated to the childhood of a genius, on the ground floor of the museum. Here is a children's violin of young talent. Exhibits change once a year. The exposition on the second floor mainly concerns Mozart's opera works, and is called "Mozart in the Theater". Numerous dioramas illustrate the history of the creation of works by the composer, theatrical stories of stage productions. Here you can see historical and modern models of costumes, listen to excerpts from the famous operas of Wolfgang Amadeus Mozart. Stage models from the late 18th to the 20th century represent multifaceted interpretations of Mozart's works. The most valuable exhibits presented on the second floor are Mozart's unfinished portrait by Joseph Lange, “Mozart at the Piano,” and Mozart’s clavichord, behind which he wrote The Magic Flute. The third floor is dedicated to the time spent by Mozart in Vienna: about his musical success, personal life and death of the legendary composer. In addition, we are talking about managing the musical heritage of the composer, his widow Constance, his sons and his sister. For example, musical instruments at the Mozart Birthplace Museum were donated by Mozart’s widow, Constance Nissen (1762-1842) and his sons Karl Thomas (1784-1858) and Franz Xavier Wolfgang (1791-1844). It tells about the Mozart cult in Austria in the 19th and 20th centuries, about the creation of the Mozart Foundation in Salzburg, which supports the composer's legacy and carries in the 21st century.
