In which city did Giuseppe Verdi's opera "Aida" premier?

"Aida" is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in the Old Kingdom of Egypt, it was commissioned by Cairo's Khedivial Opera House and had its première there on 24 December 1871, in a performance conducted by Giovanni Bottesini.

Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, Aida has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.

"Aida" met with great acclaim when it finally opened in Cairo. The costumes and accessories for the premiere were designed by Auguste Mariette, who also oversaw the design and construction of the sets, which were made in Paris by the Opéra's scene painters Auguste-Alfred Rubé and Philippe Chaperon (acts 1 and 4) and Édouard Desplechin and Jean-Baptiste Lavastre (acts 2 and 3), and shipped to Cairo. Although Verdi did not attend the premiere in Cairo, he was most dissatisfied with the fact that the audience consisted of invited dignitaries, politicians and critics, but no members of the general public.
