In 1908, Oscar Hammerstein I (grandfather of the lyricist) built the Metropolitan Opera House (originally known as the Philadelphia Opera House) to be the home of his then new opera company, the Philadelphia Opera Company. Seating more than 4,000 people, it was the largest building of its kind in the world when it was built. The Metropolitan Opera of New York City bought the Philadelphia opera house in 1910 which was used by the company for its touring productions to Philadelphia for roughly the next decade. In the 1920s, the theatre became a venue for the cinema and in the 1930s it became a ballroom. In the 1940s, a sports promoter bought the venue, covering the orchestra pit with flooring so basketball, wrestling, and boxing could take place. This venture closed after attendance waned following a decline in the quality of the opera house's neighborhood. The building was sold to Reverend Thea Jones for use as a church in 1954. The church's congregation eventually decreased and the church was unable to afford to maintain the rapidly deteriorating building. In 1994 the building was declared by the city to be dangerous and was to be demolished. Reverend Mark Hatcher and his church purchased the building in 1996 with the intention of repairing the building. In partnership with the North Philadelphia Community Development Corporation, the church plans to continue with further historic restoration in the future. In 2009 the opera house was the focal point of the Hidden City Festival, a festival dedicated to promoting lesser known historical sites in the Philadelphia area.
