Planners who handle the many moving parts it takes to execute a large-scale meeting should appreciate the group effort that’s required to stage an opera.

Doing so involves hundreds of people, from production and costume designers to the world’s most gifted musicians, all working together to create a theater experience starring some of the most glorious music ever written.

Meanwhile, the hosts of opera performances are some of the most beautiful venues in the world.

The following lineup of seven heavenly opera houses that accommodate group functions will have your attendees raising their glasses and singing along to La Traviata’s famous drinking song, or brindisi, which means “toast” in Italian.

La Scala, Milan, Italy
The world’s most famous opera house is the stunning La Scala, which has celebrated the art form for over two centuries.

“Entering La Scala is like breathing the air of the history of music, the same air that Verdi, Rossini, Puccini, Pavarotti, Maria Callas, Herbert von Karajan, Claudio Abbado, Luchino Visconti and many others have breathed before,” said Alberto Luchetti, who works in the venue’s marketing and fundraising department.

Luchetti described La Scala as a “living art machine,” where the most brilliant artists working today perform for visiting groups.

“This is really unique—it is always history in the making,” he said. “These are the emotions that we can offer in this legendary place, and having the chance to enjoy this absolute excellence with your group is an extraordinary privilege.”

Groups can book great seats in advance for live performances, which are at the center of corporate events here. Upcoming operas include Verdi’s Nabucco and Handel’s Tamerlane.

Groups may also arrange a pre-curtain guided backstage tour, a cocktail reception during intermission in the on-site museum, which showcases La Scala memorabilia, and a dinner after the performance in the Toscanini Foyer.

“On special occasions, artists can be invited as special guests to the dinner,” Luchetti said, adding that playbills signed by opera stars and customized merchandising from La Scala Shop, as well as company branding on playbills, are all possibilities.

“When we do not have a performance in the main hall, it is possible to organize special chamber concerts—usually voice and piano—in the foyers or in the museum, in partnership with the best pupils of our academia.”

Lyric Opera House, Chicago
Chicago’s historic Lyric Opera House, a hybrid of Art Nouveau and Art Deco designs, is among the world’s most gorgeous buildings.

Built in 1929, the home to Lyric Opera of Chicago offers “a majestic setting for entertaining on any scale,” according to Eleanor Sanchez, presentation and events coordinator.

“Dinners onstage at the Lyric Opera House are incredibly unique,” she said. “Guests can listen to an aria before watching the backdrop rise to reveal their banquet on stage. We have beautiful in-house chandeliers that can be lowered over the banquet setting. During our opera season, set pieces and props can adorn the stage and enhance the decor and guest experience.”

Events here, she added, also benefit from in-house lighting and sound capabilities that can help a planner’s bottom line.

Among the opera house’s gathering spaces for events, including cocktail receptions and meetings of all sizes (with or without live stream), are the lobby, grand foyer, four private dining rooms and 3,563-seat Ardis Krainik Theatre, the second-largest opera auditorium in North America.

“Opera singers who are enrolled in Lyric’s Ryan Opera Center are available to perform at events,” Sanchez said, adding that a group tour can also be arranged, including a close-up look at the backstage area, wigs, makeup and wardrobe closet.

Group tickets are available, and an opera can be incorporated into any event. Upcoming performances include Gounod’s Faust, Verdi’s Rigoletto, Bellini’s I Puritani and Wagner’s Die Walkure.

Sydney Opera House, Australia
The Sydney Opera House, the most distinctive of opera venues with its iconic sails, features a full calendar of events, including Wagner’s Parsifal and a special concert of opera highlights starring world-renowned soprano Anna Netrebko later this year.

“We are able to tailor an opera house experience for group events of any size, whether it be tours, dining at one of our six on-site restaurants, show tickets or a combination of all,” said Sophie Garrett, spokeswoman for the venue.

There are also packages such as Taste of Opera, which offers a private opera recital as part of a tour or evening meal function.
