Opposite St James's Park, next to the Wellington Barracks, you'll find the Guards Museum, which explores the history of the Guards regiments of the British Army.
The museum has over 30 displays of uniforms, weapons and tableaux depicting famous battles fought by the Guards, from the English Civil War to the present day.
The museum also houses a collector's paradise - a whole shop dedicated to toy soldiers.
Opens daily except Friday and ceremonial days all day
