I made a visit to the Guards Museum. Situated between the Guards Chapel and Wellington Barracks, Birdcage Walk, London.
An excellent introductory video explains the precedence of the Guards regiments, the different arrangement of buttons and other uniform differences.
It contains a great deal of exhibits which document the history of the five guards regiments: Grenadier, Coldstream, Scots, Irish and Welsh Guards. The exhibits are very well lit and organised to present a chronological history of the five Guards regiments.
The collection of medals is excellent, with several Victoria Cross awards and the George Cross posthumously awarded to Arthur Frederick Crane Nicholls (Coldstream Guards).
The museum is well worth a visit, with a very reasonable admission price.
