It was the only building left standing in Swansea's Castle Street vicinity after the Nazi German Luftwaffe bombing raids during the Second World War.

Two hundred seats were removed from the back of the stalls to create a foyer which meant the small circle had no overhang.

By the end of the 1970s Swansea had only two other cinemas (the ODEON on The Kingsway and a small independent operating in a chapel).

In 1982 the lease of the Castle was acquired by Circle Cinemas of Cardiff who renamed it the FILMCENTA and installed new projection equipment and Dolby Stereo and started to exhibit popular mainstream blockbusters.

This meant that it no longer showed a film exclusively and its audience chose to go to the multiplex with its modern facilities.
