The illustrated Maria Callas - Gli anni della Scala, published by Allemandi for the occasion, "documents the ten unforgettable seasons that changed the way opera presents itself as a high synthesis of theatre and music to today's sensitiveness," as described on the venue's website.

Costumes worn by Callas in performances at La Scala will also be displayed in the Theatre Museum and the Arturo Toscanini Boxes Foyer from September 14 to January 31.

A second exhibition, running until November 30, will contain photographs of Callas off stage, most of them new to the public.

September 16, the day on which she died, will see the world premiere of Philippe Kohly's film Callas, in the opera house's auditorium. All three screenings, to which a limited number of tickets will be available, are free.

Maria Callas died in 1977 at age 53.
