The Romanian composer, conductor, singer and teacher George Stephănescu (1843-1925) was the founding director of this company.

The first production by the newly formalized company was of Wagner's Lohengrin, conducted by George Enescu.

This building, with a capacity of 952 seats and designed by Octav Doicescu [ro] and Paraschiva Iubu, became the new performance venue for the Romanian Opera.

The opera company gave its first performance in this theatre on 9 January 1954, Tchaikovsky's The Queen of Spades.
