The Santander Performing Arts Center (formerly known as the Rajah Theatre or Rajah Temple, and Sovereign Performing Arts Center) is a historic theatre in Reading, Pennsylvania, United States. It is the current home of the Reading Symphony Orchestra and the "Broadway on 6th St" annual series of musicals and plays.^[1]

Built in 1922 under the name The Rajah Temple, it was second structure owned by the Shriners that operated as a dual purpose public theatre and temple for the masons in the city of Reading and the third building to be known as the Rajah Temple.^[2] The first Rajah Temple was originally the St. Matthew Lutheran Church property at Pearl and Franklin Streets, which was purchased by the Shriners in 1892.^[2] In 1917 the Shriners purchased the Academy of Music, a theatre in Reading, and relocated their temple to that location where it continued to operate as the Rajah Temple and Rajah Theatre for public performances and freemason events.^[2] That structure was destroyed by fire on May 21, 1921.^[2]

In November 1922 construction began on the current theatre. It operated as a performance arts venue for vaudeville, operas, concerts, plays, and a movie theatre at various times during the 20th century.^[2] In 2000 the Berks County Convention Center Authority oversaw the acquisition and renovation of the theatre by Sovereign Bank; who rebranded the theater as the Sovereign Performing Arts Center.^[1] Sovereign Bank was rebranded as Santander Bank on October 17, 2013; and the performing arts center for which it has naming rights were also rebranded.^[3] It is now the home of the Reading Symphony Orchestra and the "Broadway on 6th St" annual series of musicals and plays.^[1]
