There are several excellent performing arts venues in Rome. At least five regularly stage operas. At the top of the list is Teatro dell’Opera di Roma. When opened in 1880, it was called Costanzi Theatre in honor of Domenico Costanzi, the building’s architect and first manager. The 1,600 seat theater has been rebuilt and renovated a few times. The latest was in 1946. The highly revered house stages productions by international performers of opera, ballet and concerts.
