This is the older of the two opera houses in Paris, known as L’Opéra Garnier (or Palais Garnier) after its architect, Charles Garnier. He is not, as far as I can tell, related in any way to the hair care line which shares his name (now owned by French company L’Oréal).
The building, located in the 9th district, was partially opened in 1867 for the International Exposition. It officially opened in 1875 and stands as one of the great examples of Haussmannian architecture.
