In 2004, the city of Vienna's Wien Holding company undertook the total renovation of the Mozarthaus and redesigned it for visitors, and this was completed in time for Mozart Year 2006, the 250th anniversary of his birth.[1][2] Following a complete refurbishment, the entire building (including the expanded basement) became a centre dedicated to the composer's life and work, incorporating the rooms occupied by Mozart himself. This process was overseen by the Vienna Museum. The design of the historical courtyard was essentially destroyed by the installation of an elevator.
