In addition to the five original galleries which house 5,000 objects in the permanent displays and the more recent Peace Gallery, the museum also includes the Hall of Steel, a giant staircase whose walls are decorated with trophy displays composed of 2,500 objects reminiscent of the historical trophy displays erected by the Tower Armouries from the 17th century.
Udover de fem originale gallerier, som rummer 5.000 genstande i den permanente udstilling og den nyere Peace Gallery, har museet også Hall of Steel, en kæmpe trappe, hvis vægge er dekoreret med 2.500 genstande, der minder om de historiske udstillinger, der blev etableret i Tower Armouries i det 1600-tallet.
