The Teatro delle Dame, also known as the Teatro Alibert (its original name), was a theatre in Rome built in 1718 and located on what is now the corner of Via D'Alibert and Via Margutta. In the course of its history it underwent a series of reconstructions and renovations until it was definitively destroyed by a fire in 1863. In their 18th-century heyday, the Teatro delle Dame and its rival, the Teatro Capranica, were the leading opera houses in Rome and saw many world premieres performed by some of the most prominent singers of the time.
