Imperial War Museum
Located in Lambeth
At the risk of stating the obvious, the National Army Museum is about the army while the Imperial War Museum is about war.
As such I found the IWM to be a more sombre experience, you won’t see as many displays of colourful uniforms
but will learn more about the depressing realities of conflict.
The IWM is also larger and focuses only on the 20th Century and onwards, allowing
them to cover their subjects in more depth.
