The Teatro dell'Opera di Roma (Rome Opera House) is an opera house in Rome, Italy. Originally opened in November 1880 as the 2,212 seat Costanzi Theatre, it has undergone several changes of name as well modifications and improvements. The present house seats 1,600.
The Teatro dell'Opera was originally known as the Teatro Costanzi after the contractor who built it, Domenico Costanzi (1810-1898). It was financed by Costanzi, who commissioned the Milanese architect Achille Sfondrini (1836-1900), a specialist in the building and renovation of theatres. The opera house was built in eighteen months, on the site where the house of Heliogabalus stood in ancient times, and was inaugurated on 27 November 1880 with a performance of Semiramide by Gioachino Rossini.
Designing the theatre, Sfondrini paid particular attention to the acoustics, conceiving the interior structure as a "resonance chamber", as is evident from the horseshoe shape in particular. With a seating capacity of 2,212, the house had three tiers of boxes, an amphitheatre and two separate galleries, surmounted by a dome adorned with splendid frescoes by Annibale Brugnoli.
Costanzi was obliged to manage the theater himself. Under his direction, and despite financial problems, the opera house held many world premieres of operas, including Cavalleria rusticana by Pietro Mascagni on 17 May 1890. For a brief period the theatre was managed by Costanzi's son, Enrico, who gained renown by organizing another great premiere, that of Tosca by Giacomo Puccini on 14 January 1900.
