The Teatro Regio (Royal Theatre) is a prominent opera house and opera company in Turin. Its season runs from October to June with the presentation of eight or nine operas given from five to twelve performances of each. Several buildings provided venues for operatic productions in Turin from the mid-16th century, but it was not until 1713 that a proper opera house was considered, and under the architect Filippo Juvarra planning began. However, the cornerstone was not laid until the reign of Charles Emmanuel III in 1738 after Juvarra's death. The work was supervised by Benedetto Alfieri until the theatre was completed.
