Newark Symphony Hall is a performing arts center located at 1020 Broad Street in Newark, New Jersey. Built in 1925, it was added to the National Register of Historic Places in 1977. It was known for many years as The Mosque Theater, and is the former home of the New Jersey Symphony Orchestra, New Jersey State Opera and the New Jersey Ballet Company. The Hall is owned by the Essex County Improvement Authority and is operated by the non-profit Newark Performing Arts Corporation (NPAC). Design and construction Originally built in 1925 by the Shriners at a cost of more than $2 million as Salaam Temple and colloquially known as The Mosque, the four-story building has been Newark Symphony Hall since 1964. The interior features Greek and Egyptian motifs, marble columns, a crystal chandelier, gold-leaf fret work and two-columned side promenades. The neo-classical building was designed by Frank Grad, a prominent Newark architect, whose work includes the Lefcourt Newark Building and many others downtown. The 3,500-seat main concert hall is named for Sarah Vaughan, a native Newarker, and is renowned for its acoustics. Newark Stage is a 200-seat black box theater used by theatrical productions. The Terrace Ballroom is used for receptions. The Studio is a rehearsal space. The Dance Studio is home to one of three facilities in the state used by the school of the Garden State Ballet, founded in 1951.
