The Metropolitan Opera House (colloquially The Met) is an opera house located on Broadway at Lincoln Square in the Upper West Side of Manhattan in New York City. Part of Lincoln Center for the Performing Arts, the theater was designed by Wallace K. Harrison. It opened in 1966, replacing the original 1883 Metropolitan Opera House at Broadway and 39th St. With a seating capacity of approximately 3,800, the house is the largest repertory opera house in the world. Home to the Metropolitan Opera Company, the facility also hosts the American Ballet Theatre in the summer months.
