Metropolitan Opera House (Philadelphia)

The Metropolitan Opera House is a historic opera house and current pop concert venue located in Philadelphia, Pennsylvania. It has been used for many different purposes since originally opening in 1908. In December 2018, after 110 years of operation and a major renovation, it reopened as a concert venue. Now known as The Met it is managed by Live Nation Philadelphia.

Built over the course of just a few months in 1908, it was the ninth opera house built by impresario Oscar Hammerstein I. It was initially the home of Hammerstein's Philadelphia Opera Company, and called the "Philadelphia Opera House". Hammerstein sold it to the Metropolitan Opera of New York City in 1910, who renamed it. The Met used it through the 1920s, after which it changed hands again and various other opera companies used it through 1934.

For eight decades it remained in constant use from opera house to movie theater, to a ballroom, a sports venue, a mechanic training center, and a church. The building, by then in serious disrepair, was unused and vacant for almost eight years from 1988 until 1995, when it became the "Holy Ghost Headquarters Revival Center at the Met". The church stabilized much of the building, eventually paving the way for the latest renovation of the facility in 2017–2018.

The opera house has been included on the National Register of Historic Places since 1972.
