It is named after the artist Frank Brangwyn, whose British Empire Panels, originally intended for the House of Lords, are displayed there.

[1] The British Empire Panels are sixteen large paintings by Frank Brangwyn which were commissioned in 1924 for the Royal Gallery of the House of Lords, to commemorate the First World War.

He chose to create a "decorative painting representing various Dominions and parts of the British Empire", and five finished panels were displayed in 1930.

[8] Additionally, the BBC has filmed some scenes from the Doctor Who episodes "Silence in the Library" and "Forest of the Dead", as well as "The Big Bang".

[10] The hall has a concert organ, with four manuals, designed by Henry Willis & Sons[11] which was originally built in 1921 for the Elite Picture Theatre, Nottingham.
