The Santander Arena (formerly known as the Sovereign Center) is a 7,083-seat multi-purpose arena, in Reading, Pennsylvania. It was built in 2001. The arena sits on the former site of the Astor Theatre; one of several grand movie and theater palaces built in Reading in the early 20th century. Closed in 1975, the theater sat vacant for over two decades. In 1998, the Astor was demolished to make room for the Santander Arena. Early in construction, steps were taken to retain mementos of the Astor, including its ornate Art Deco chandelier and gates.
